  • Product overview

    Abcam’s IGF1 Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme linked immunosorbent assay for the quantitative measurement of Human IGF1 in serum, plasma, and cell culture supernatants.

    This assay employs an antibody specific for Human IGF1 coated on a 96-well plate. Standards and samples are pipetted into the wells and IGF1 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human IGF1 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of IGF1 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

     Get results in 90 minutes with Human IGF1 ELISA Kit (ab211651) from our SimpleStep ELISA® range.

ab100545-Human IGF1 ELISA Kit for Human Saliva

Excellent Excellent 5/5 (Ease of Use)
This kit worked successfully to quantify IGF1 protein in human saliva. We obtained valid results for all of our wells and were able to use these results to compare to them to amounts of BDNF and cortisol in saliva. The results from this kit greatly contributed to my senior thesis project, which looked at differences in IGF1 levels across a 3-month exercise intervention in older adults. We will very likely be ordering this kit again in for future analyses of IGF1.

This kit is designed to measure free IGF1. IGF-1 is usually bound to IGFBPs in the serum/plasma, so if you would like to measure total IGF1, it is advisable to release the analytes by performing an extraction procedure such as acid-ethanol treatment (P...
