UniProt Protein Function:
NF1: a Ras-GAP, highly expressed in developing neural cells. Possesses tumor suppressor activity, presumably by virtue of its GTPase activating domain. Neurofibromin is phosphorylated in response to EGF in CNS cells and cell lines. Defects in NF1 are the cause of type 1 neurofibromatosis (NF1), Watson syndrome, and familial spinal neurofibromatosis. NF1 is one of the most frequent autosomal dominant diseases. Four alternatively spliced isoforms have been described.Protein type: GAPs, Ras; Tumor suppressor; GAPs; Nucleolus; Motility/polarity/chemotaxisCellular Component: axon; cytoplasm; dendrite; membrane; neuron projection; nucleolus; nucleus; postsynaptic density; protein complexMolecular Function: GTPase activator activity; microtubule binding; phosphatidylcholine binding; phosphatidylethanolamine binding; protein binding; syndecan bindingBiological Process: actin cytoskeleton organization and biogenesis; adrenal gland development; amygdala development; artery morphogenesis; brain development; camera-type eye morphogenesis; cell communication; cerebral cortex development; cognition; collagen fibril organization; extracellular matrix organization and biogenesis; forebrain astrocyte development; forebrain morphogenesis; heart development; induction of apoptosis via death domain receptors; liver development; MAPKKK cascade; metanephros development; myelination in the peripheral nervous system; negative regulation of angiogenesis; negative regulation of astrocyte differentiation; negative regulation of cell migration; negative regulation of cell proliferation; negative regulation of cell-matrix adhesion; negative regulation of endothelial cell proliferation; negative regulation of fibroblast proliferation; negative regulation of MAP kinase activity; negative regulation of MAPKKK cascade; negative regulation of neuroblast proliferation; negative regulation of neurotransmitter secretion; negative regulation of oligodendrocyte differentiation; negative regulation of osteoclast differentiation; negative regulation of protein kinase activity; negative regulation of Rac protein signal transduction; negative regulation of Ras protein signal transduction; negative regulation of transcription factor import into nucleus; neural tube development; osteoblast differentiation; peripheral nervous system development; phosphoinositide 3-kinase cascade; pigmentation; positive regulation of adenylate cyclase activity; positive regulation of apoptosis; positive regulation of endothelial cell proliferation; positive regulation of GTPase activity; positive regulation of neuron apoptosis; Ras protein signal transduction; regulation of angiogenesis; regulation of blood vessel endothelial cell migration; regulation of bone resorption; regulation of cell proliferation; regulation of cell-matrix adhesion; regulation of gene expression; regulation of glial cell differentiation; regulation of GTPase activity; regulation of long-term neuronal synaptic plasticity; regulation of MAPKKK cascade; regulation of neuron differentiation; regulation of synaptic transmission, GABAergic; response to hypoxia; Schwann cell development; signal transduction; skeletal muscle development; smooth muscle development; spinal cord development; sympathetic nervous system development; visual learning; wound healing

*Note: The below protocol is a sample protocol. Protocols are specific to each batch/lot. For the correct instructions please follow the protocol included in your kit.
Allow all reagents to reach room temperature (Please do not dissolve the reagents at 37°C directly). All the reagents should be mixed thoroughly by gently swirling before pipetting. Avoid foaming. Keep appropriate numbers of strips for 1 experiment and remove extra strips from microtiter plate. Removed strips should be resealed and stored at -20°C until the kits expiry date. Prepare all reagents, working standards and samples as directed in the previous sections. Please predict the concentration before assaying. If values for these are not within the range of the standard curve, users must determine the optimal sample dilutions for their experiments. We recommend running all samples in duplicate.
Step
1.
Add Sample: Add 100µL of Standard, Blank, or Sample per well. The blank well is added with Sample diluent. Solutions are added to the bottom of micro ELISA plate well, avoid inside wall touching and foaming as possible. Mix it gently. Cover the plate with sealer we provided. Incubate for 120 minutes at 37°C.
2.
Remove the liquid from each well, don't wash. Add 100µL of Detection Reagent A working solution to each well. Cover with the Plate sealer. Gently tap the plate to ensure thorough mixing. Incubate for 1 hour at 37°C. Note: if Detection Reagent A appears cloudy warm to room temperature until solution is uniform.
3.
Aspirate each well and wash, repeating the process three times. Wash by filling each well with Wash Buffer (approximately 400µL) (a squirt bottle, multi-channel pipette,manifold dispenser or automated washer are needed). Complete removal of liquid at each step is essential. After the last wash, completely remove remaining Wash Buffer by aspirating or decanting. Invert the plate and pat it against thick clean absorbent paper.
4.
Add 100µL of Detection Reagent B working solution to each well. Cover with the Plate sealer. Incubate for 60 minutes at 37°C.
5.
Repeat the wash process for five times as conducted in step 3.
6.
Add 90µL of Substrate Solution to each well. Cover with a new Plate sealer and incubate for 10-20 minutes at 37°C. Protect the plate from light. The reaction time can be shortened or extended according to the actual color change, but this should not exceed more than 30 minutes. When apparent gradient appears in standard wells, user should terminatethe reaction.
7.
Add 50µL of Stop Solution to each well. If color change does not appear uniform, gently tap the plate to ensure thorough mixing.
8.
Determine the optical density (OD value) of each well at once, using a micro-plate reader set to 450 nm. User should open the micro-plate reader in advance, preheat the instrument, and set the testing parameters.
9.
After experiment, store all reagents according to the specified storage temperature respectively until their expiry.
When carrying out an ELISA assay it is important to prepare your samples in order to achieve the best possible results. Below we have a list of procedures for the preparation of samples for different sample types.
Sample Type
Protocol
Serum
If using serum separator tubes, allow samples to clot for 30 minutes at room temperature. Centrifuge for 10 minutes at 1,000x g. Collect the serum fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles. If serum separator tubes are not being used, allow samples to clot overnight at 2-8°C. Centrifuge for 10 minutes at 1,000x g. Remove serum and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles.
Plasma
Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples at 4°C for 15 mins at 1000 × g within 30 mins of collection. Collect the plasma fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles. Note: Over haemolysed samples are not suitable for use with this kit.
Urine & Cerebrospinal Fluid
Collect the urine (mid-stream) in a sterile container, centrifuge for 20 mins at 2000-3000 rpm. Remove supernatant and assay immediately. If any precipitation is detected, repeat the centrifugation step. A similar protocol can be used for cerebrospinal fluid.
Cell culture supernatant
Collect the cell culture media by pipette, followed by centrifugation at 4°C for 20 mins at 1500 rpm. Collect the clear supernatant and assay immediately.
Cell lysates
Solubilize cells in lysis buffer and allow to sit on ice for 30 minutes. Centrifuge tubes at 14,000 x g for 5 minutes to remove insoluble material. Aliquot the supernatant into a new tube and discard the remaining whole cell extract. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C.
Tissue homogenates
The preparation of tissue homogenates will vary depending upon tissue type. Rinse tissue with 1X PBS to remove excess blood & homogenize in 20ml of 1X PBS (including protease inhibitors) and store overnight at ≤ -20°C. Two freeze-thaw cycles are required to break the cell membranes. To further disrupt the cell membranes you can sonicate the samples. Centrifuge homogenates for 5 mins at 5000xg. Remove the supernatant and assay immediately or aliquot and store at -20°C or -80°C.
Tissue lysates
Rinse tissue with PBS, cut into 1-2 mm pieces, and homogenize with a tissue homogenizer in PBS. Add an equal volume of RIPA buffer containing protease inhibitors and lyse tissues at room temperature for 30 minutes with gentle agitation. Centrifuge to remove debris. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C.
Breast Milk
Collect milk samples and centrifuge at 10,000 x g for 60 min at 4°C. Aliquot the supernatant and assay. For long term use, store samples at -80°C. Minimize freeze/thaw cycles.
