产品概述
Human C1 inhibitor ELISA Kit (ab224883) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of C1 inhibitor protein in cell culture supernatant, cit plasma, edta plasma, hep plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human C1 inhibitor with 10.9 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

说明
C1 inhibitor, also known as C1 esterase inhibitor and Serpin G1, is a protease inhibitor belonging to the serpin superfamily, and is encoded by the gene SERPING1. C1 inhibitor is a 478 -amino acid containing protein, and is heavily glycosylated with an approximate 105 kDa molecular mass. The primary function of C1 inhibitor is the inhibition of the classical complement cascade to suppress spontaneous activation by forming an inactive complex with C1r and C1s proteases. In addition, C1 inhibitor also inactivates proteases of the fibrinolytic, clotting, and kinin pathways. The levels of C1 inhibitor in blood fluctuate during inflammation, and deficiencies of C1 inhibitor are associated with hereditary angioedema.

C1 inhibitor functions as a regulator of the activation of the classical complement pathway and of the contact activation system of kinin generation and coagulation. Its primary biologically relevant target proteinases are C1r, C1s, coagulation factors XIa and XIIa, and plasma kallikrein. C1-inhibitor consists of one polypeptide chain and has a molecular mass of 104 kDa. -

Interpolated concentrations of native C1 inhibitor in human serum and plasma samplesThe concentrations of C1 inhibitor were measured in duplicates, interpolated from the C1 inhibitor standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 1:4000, plasma (citrate) 1:4000, plasma (EDTA) 1: 4,000, and plasma (heparin) 1:8000. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean C1 inhibitor concentration was determined to be 9,502 ng/mL in serum, 8,496 ng/mL in plasma (citrate), 4,285 ng/mL in plasma (EDTA), and 26,756 ng/mL in plasma (heparin).

Interpolated concentrations of native C1 inhibitor in human HepG2 cell culture supernatantHepG2 cells were cultured for 5 days in DMEM media containing 10% FBS and 1% NEAA. The concentrations of C1 inhibitor were measured in duplicate and interpolated from the C1 inhibitor standard curve and corrected for sample dilution. Undiluted samples are 18.75%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean C1 inhibitor concentration was determined to be 1,303 pg/mL.
