The Human Neurokinin B (NKB) ELISA Kit is a highly sensitive and specific assay for the accurate quantification of NKB levels in human samples such as serum, plasma, and cell culture supernatants. This kit provides reliable and reproducible results, making it suitable for a variety of research applications. Neurokinin B is a neuropeptide that plays a crucial role in various physiological processes, such as regulating neurotransmitter release and modulating pain perception. Imbalances in NKB levels have been associated with conditions such as chronic pain, neurological disorders, and reproductive dysfunction, making it a valuable biomarker for studying these conditions and evaluating potential therapeutic interventions.
The Human NKB ELISA Kit from Assaygenie offers researchers a powerful tool for studying the role of NKB in health and disease, providing accurate and precise measurements to further the understanding of NKB-mediated pathways and potential treatment strategies.

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.
Step
Procedure
1
Reagent & Plate Preparation: Equilibrate TMB substrate for 30 minutes at room temperature. Prepare standards, samples (minimum 1:2 dilution), blanks, assign wells, and pre-wash the plate twice.
2
Sample & Biotin-Antibody Binding: Add 50 µL standard or sample followed by 50 µL biotin-labeled antibody to each well. Mix gently and incubate at 37°C for 45 minutes.
3
Washing: Wash the plate 5 times with wash buffer, allowing 1 minute soak time per wash.
4
Color Development: Add TMB substrate and incubate in the dark at 37°C for 10-20 minutes until color develops.
5
Stop Reaction: Add stop solution to terminate the reaction. The color changes from blue to yellow immediately.
6
Reading: Measure absorbance at 450 nm using a microplate reader.
Sample Type
Protocol
Serum
Allow blood to clot, centrifuge at 1000 × g for 20 minutes, collect supernatant and store appropriately.
Plasma
Collect using EDTA anticoagulant, centrifuge at 1000 × g for 15 minutes at 2–8°C and collect plasma.
Cell Culture Supernatant
Centrifuge at 1000 × g for 20 minutes at 4°C and collect clarified supernatant.
Cell Lysate
Lyse cells using recommended lysis buffer with protease inhibitors, centrifuge at 10,000 rpm for 10 minutes, and collect protein supernatant.
Tissue Homogenate
Homogenize tissue in PBS with protease inhibitors, centrifuge at 5000 × g for 5 minutes, and collect supernatant.
Other Sample Types
Centrifuge samples at 1000 × g for 15 minutes at 2–8°C and collect supernatant. For additional guidance, please contact techsupport@assaygenie.com.
