Abcam’s Factor H Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Human Factor H in urine, saliva, milk, plasma, serum, cerebrospinal fluid and cell culture supernatants.
A Factor H specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a Factor H specific 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 Factor H captured in plate.

Standard curve with background signal subtracted (duplicates; +/- SD).
Factor H measured in culture supernatants (tested at dilution range 1/1-1/30; duplicates +/- SD).
Factor H measured in biological fluids (duplicates +/- SD). Human serum and plasma were tested at dilution range of 1/50000-1/1500000. Other bilogical fluids were tested at 1/1-1/500 and gave measurable values (milk: 400, saliva: 200, CSF: 2000 and urine: 40 ng per mL).
