Anti-a1-Acid Glycoprotein (Orosomucoid)

alpha 1-Acid Glycoprotein (AGP, also OMD/Orosomucoid) is a 40-46kD member of the immunocalin subfamily, lipocalin family of molecules. In mouse, circulating AGP is principally the product of hepatocytes that originates from multiple related genes (AGP-1, -2 & -3 in Mus musculus). Circulating AGP-1 and -2 are both 189aa in length, the principal sources of protein, and show 83% aa identity, AGP-3 contributes little to the AGP pool. In mouse blood, AGP is normally 200-400ug/ml. In response to inflammatory mediators (IL-6, IL-1), its concentration will rise 2 to 10 fold. More importantly, a complex glycosylation pattern will also change, transitioning from modestly branched to highly branched oligosaccharides. This change is reflected in its bioactivity, which has been shown to be a function of carbohydrate branching. AGP is generally considered to be a suppressor of inflammation. Rat and human AGP share only 70% and 47% aa identity with mouse AGP, respectively. Applications: Suitable for use in ELISA and Western Blot. Other applications not tested. Recommended Dilutions: ELISA: 0.5-1ug/ml. The detection limit is ~0.3ng/well., Western Blot: 1ug/ml, Optimal dilutions to be determined by the researcher. Storage and Stability: Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile PBS. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
