  • 製品の概要

    Abcam’s Retinol binding protein 4 (RBP4) Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Retinol binding protein 4 concentrations in plasma, serum, saliva, urine, milk, cerebrospinal fluid and cell culture supernatants.

    A Retinol binding protein 4 specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a Retinol binding protein 4specific biotinylated detection antibody is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Conjugate is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize Streptavidin-Peroxidase enzymatic reaction. TMB is catalyzed by Streptavidin-Peroxidase to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the amount of Retinol binding protein 4 captured in plate.

    Get higher sensitivity in only 90 minutes with Human Retinol Binding Protein 4 ELISA Kit (ab196264) from our SimpleStep ELISA® range.

Thank you for your patience with this reply.

I heard back from the lab that for the kits below, the antibodies were raised against recombinant proteins. The epitopes have not been mapped.
