catalog number :
MBS7252797
products type :
ELISA Kit
products full name :
Human Homocysteine ELISA Kit
products short name :
Homocysteine
specificity :
This assay has high sensitivity and excellent specificity for detection of HCY. No significant cross-reactivity or interference between HCY and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between HCY and all the analogues, therefore, cross reaction may still exist in some cases.
storage stability :
Store all reagents at 2-8 degree C.
other info1 :
Samples: Serum, plasma, cell culture supernatants, body fluid and tissue homogenate. Assay Type: Competitive. Sensitivity: 1.0 umol/L.
products description :
Intended Uses: This HCY ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Human HCY. This ELISA kit for research use only, not for therapeutic or diagnostic applications!. Principle of the Assay HCY ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-HCY antibody and an HCY-HRP conjugate. The assay sample and buffer are incubated together with HCY-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the HCY concentration since HCY from samples and HCY-HRP conjugate compete for the anti-HCY antibody binding site. Since the number of sites is limited, as more sites are occupied by HCY from the sample, fewer sites are left to bind HCY-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The HCY concentration in each sample is interpolated from this standard curve.
