Description: Homocysteine is an amino acid intermediate that is synthesized from methionine via S-adenosylmethionine (SAM) and S-adenosylhomocysteine (SAH). Elevated levels of homocysteine can indicate a risk for numerous diseases, including vascular and heart disease. Our Homocysteine ELISA is designed for detection and quantitation of homocysteine in plasma, serum, lysates, or biological fluid samples. This assay is a competitive ELISA where samples and an anti-homocysteine antibody are added to a plate coated with a homocysteine conjugate. The sample and conjugate compete for antibody binding, which generates a reverse curve. Samples with high homocysteine levels will bind to most of the antibody, which gets washed away and results in a low OD, while samples with low homocysteine levels will leave more antibody available to bind to the conjugate, producing a high signal.

Description: Cell Biolabs? Aflatoxin Competitive ELISA Kit provides a convenient method for the detection of total Aflatoxin B1 and Aflatoxin B2 adducts in protein samples. First, an AFB1 conjugate is coated on an ELISA plate.  The unknown AFB1/2 samples or AFB1-BSA standards are then added to the AFB1 conjugate preabsorbed ELISA plate.  After a brief incubation, an anti-AFB1/2 monoclonal antibody is added, followed by an HRP conjugated secondary antibody.  The total content of AFB1 plus AFB2 in unknown samples is determined by comparison with a predetermined AFB1-BSA standard curve.

Description: Our Cholic Acid ELISA Kit is designed for detection and quantitation of cholic acid in plasma, serum, urine, feces, or lysates. This assay is a competitive ELISA where unknown samples are added to a plate pre-adsorbed with a cholic acid conjugate. An anti-cholic acid antibody is added, which is then detected by an HRP conjugated secondary antibody. Cholic acid levels in unknown samples are calculated based on a cholic acid standard curve.

Description: Our Chenodeoxycholic Acid ELISA Kit is designed for detection and quantitation of chenodeoxycholic acid in plasma, serum, feces, or lysates. This assay is a competitive ELISA where unknown samples are added to a plate pre-adsorbed with a chenodeoxycholic acid conjugate. An anti-chenodeoxycholic acid antibody is added, which is then detected by an HRP conjugated secondary antibody. Chenodeoxycholic acid levels in unknown samples are calculated based on a chenodeoxycholic acid standard curve.

Description: Our Human Haptoglobin ELISA Kit is a sandwich ELISA for the detection of human haptoglobin in plasma, serum, lysates, and other biological fluids. Samples or standards are added to an anti-human Hp antibody coated plate followed by the addition of an anti-human Hp antibody. An HRP conjugated secondary antibody is then added for detection and the absorbance is read at 450nm. The level of haptoglobin in samples is determined based on the provided human haptoglobin standard curve.

Description: Our Human Ceruloplasmin ELISA Kit is a sandwich ELISA for the detection of human haptoglobin in plasma, serum, lysates, and other biological fluids. Samples or standards are added to an anti-human Cp antibody coated plate followed by the addition of an anti-human Cp antibody. An HRP conjugated secondary antibody is then added for detection and the absorbance is read at 450nm. The level of ceruloplasmin in samples is determined based on the provided human ceruloplasmin standard curve.

Description: The Human ApoAI ELISA Kit is an enzyme immunoassay developed for the detection and quantitation of human apolipoprotein in plasma, serum or other biological fluid samples.  Each kit provides sufficient reagents to perform up to 96 assays including standard curve and unknown samples.

Description: The Human ApoAII ELISA Kit is an enzyme immunoassay developed for the detection and quantitation of human apolipoprotein in plasma, serum or other biological fluid samples.  Each kit provides sufficient reagents to perform up to 96 assays including standard curve and unknown samples.
