EliKine™ Human bFGF ELISA Kit Review

The protein encoded by FGF2 gene is a member of the fibroblast growth factor (FGF) family. FGF family members bind heparin and possess broad mitogenic and angiogenic activities. This protein has been implicated in diverse biological processes, such as limb and nervous system development, wound healing, and tumor growth. The mRNA for this gene contains multiple polyadenylation sites, and is alternatively translated from non-AUG (CUG) and AUG initiation codons, resulting in five different isoforms with distinct properties. The CUG-initiated isoforms are localized in the nucleus and are responsible for the intracrine effect, whereas, the AUG-initiated form is mostly cytosolic and is responsible for the paracrine and autocrine effects of this FGF.

EliKine™ Human bFGF ELISA Kit employs a two-site sandwich ELISA to quantitate bFGF in samples. An antibody specific for bFGF has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any bFGF present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for bFGF is added to the wells. After washing, proprietary EliKine™ Streptavidin-HRP conjugates is added to the wells. Following a wash to remove any unbound streptavidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of bFGF bound in the initial step. The color development is stopped and the intensity of the color is measured.

I ordered the Human bFGF ELISA Kit from Abbkine and want to detect endogenous bFGF level in human cell culture supernatant. What is surprising is that I received the product just three days later. The technical support is very professional and patient, and they help me search the references and analyze the questions met during the experiment. Finally, I got satisfying results. The kit has high sensitivity and the price is cheaper than other brands. I want to recommend it to my friends.
