Description
Mouse INHB (Inhibin B) ELISA Kit
The Mouse INHB (Inhibin-B) ELISA Kit is specifically designed for the precise measurement of inhibin-B levels in mouse serum, plasma, and tissue culture supernatants. This kit offers exceptional sensitivity and specificity, guaranteeing consistent and accurate results for various research purposes.Inhibin-B is a key protein that plays a vital role in regulating the reproductive system, particularly in the synthesis and secretion of follicle-stimulating hormone (FSH) from the pituitary gland.
Abnormal levels of inhibin-B have been linked to disorders such as infertility, polycystic ovarian syndrome (PCOS), and ovarian cancer, making it a valuable biomarker for investigating these conditions and developing potential treatments.With its advanced technology and reliable performance, the Mouse INHB (Inhibin-B) ELISA Kit is an essential tool for researchers studying reproductive biology and related disorders in mouse models.

This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Mouse INHB. Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Mouse INHB and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Mouse INHB, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by adding Stop Solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Mouse INHB. The concentration of Mouse INHB in samples can be calculated by comparing the OD of the samples to the standard curve.
| UniProt Protein Function: | INHBA: Inhibins and activins inhibit and activate, respectively, the secretion of follitropin by the pituitary gland. Inhibins/activins are involved in regulating a number of diverse functions such as hypothalamic and pituitary hormone secretion, gonadal hormone secretion, germ cell development and maturation, erythroid differentiation, insulin secretion, nerve cell survival, embryonic axial development or bone growth, depending on their subunit composition. Inhibins appear to oppose the functions of activins. Belongs to the TGF-beta family. |

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e. g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.

- Set standard, test sample and control (zero) wells on the pre-coated plate and record theirpositions. It is recommended to measure each standard and sample in duplicate. Note: addall solutions to the bottom of the plate wells while avoiding contact with the well walls. Ensuresolutions do not foam when adding to the wells.
- Aliquot 100µl of standard solutions into the standard wells.
- Add 100µl of Sample / Standard dilution buffer into the control (zero) well.
- Add 100µl of properly diluted sample (serum, plasma, tissue homogenates and otherbiological fluids) into test sample wells.
- Cover the plate with the sealer provided in the kit and incubate for 90 min at 37°C.
- Aspirate the liquid from each well, do not wash. Immediately add 100µL of BiotinylatedDetection Ab working solution to each well. Cover the plate with a plate seal and gently mix. Incubate for 1 hour at 37°C.
- Aspirate or decant the solution from the plate and add 350µL of wash buffer to each welland incubate for 1-2 minutes at room temperature. Aspirate the solution from each well andclap the plate on absorbent filter paper to dry. Repeat this process 3 times. Note: a microplatewasher can be used in this step and other wash steps.
