Precision
Intra-assay Precision (Precision within an assay): CV%<15%      
Three samples of known concentration were tested twenty times on one plate to assess.  
Inter-assay Precision (Precision between assays): CV%<15%      
Three samples of known concentration were tested in twenty assays to assess.    
             
Linearity
To assess the linearity of the assay, samples were spiked with high concentrations of bovine FSH in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Description

Researchers can use the Bovine follicle-stimulating hormone (FSH) ELISA Kit for quantitative detection of bovine FSH in serum, plasma, and tissue homogenates. The kit's detection range is 2 mIU/mL-800 mIU/mL, with a sensitivity of 2 mIU/mL. It employs a competitive detection mechanism, where the FSH in the sample competes with a labeled FSH for a limited number of antibody binding sites. This competition creates an inverse relationship between the concentration of FSH in the sample and the signal output, allowing for precise quantification. The assay requires 50-100 μL of sample and can be completed in 1-5 hours, with results measured at 450 nm wavelength. This bovine FSH ELISA kit has been used in the experimental setup of several papers.

Target Background

Function
(From Uniprot)
Together with the alpha chain CGA constitutes follitropin, the follicle-stimulating hormone, and provides its biological specificity to the hormone heterodimer. Binds FSHR, a G protein-coupled receptor, on target cells to activate downstream signaling pathways. Follitropin is involved in follicle development and spermatogenesis in reproductive organs.

  2. the novel cis-regulatory element generated by the c.-1539_-1538delGGinsTTAACT mutations might play an important role in repressing FSHB transcription, possibly leading to reduced fertility PMID: 26478576

  4. The shift in FSH isoforms toward a greater abundance of the less acidic isoforms appears to be a key component in determining the capability for producing a preovulatory rise in estradiol. PMID: 18400447
  5. The effect of a single nucleotide polymorphism of the follicle stimulating hormone beta chain on bull fertility and semen quality is reported. PMID: 18829190
