Product Specific Information

By sandwich ELISA, MIA1404 can be used as a detection antibody with Product # 710263 or # 701239 as a coating antibody, to generate a matched pair. Using these matched pairs, recombinant human Apo A-1, but not recombinant mouse Apo A-1, was detected. MIA1404 can be used to detect Apo A-1 from serum samples. To increase sensitivity of sandwich ELISAs with MIA1404, a biotinylated detection antibody followed by Streptavidin-HRP is recommended.

By Western blot, MIA1404 detects recombinant human Apo A-1, but not recombinant mouse Apo A-1. MIA1404 is also recommended for detecting endogenous Apo A-1 by Western blot.

MIA1404 was formerly sold as a Seradyn product.

Target Information

Apolipoprotein A-1 (apo A-1) in human plasma is a major protein component of high density lipoprotein (HDL). The molecular mass is 24 kDa. Apo A-1 is a cofactor for enzymes involved in the normal turnover of cholesterol and is produced in the liver. Plasma concentration is 270-380 mg/100 mL.
