Zn-α2-glycoprotein (ZAG) is a soluble protein that was originally isolated from human plasma. ZAG is related to class I major histocompatibility complex (MHC) proteins, which are involved in peptide presentation to cytoxic T-cells during immune surveillance. Besides plasma, ZAG is found in liver, as well as bodily fluids such as sweat, saliva, cerebrospinal fluid, seminal plasm, milk, ammniotic fluid, and urine. In addition, ZAG is found in 40% of breast carcinomas, and in varous tumor cells. In plasma, ZAG's lipid binding ability may be important for lipid store homeostasis. Additional functions of ZAG may be involved in the regulation of cell proliferation. In vitro, ZAG has ribonuclease activity that is comparable to onconase and less than RNase A. ZAG may also regulate cell adhesion, since Tu-138 oral squamouse cells can attach to a ZAG substratum. This attachment inhibits cell proliferation and may involve interaction with integrin α5β1 receptors. Thus, ZAG may be a multi-functional protein involved in lipid storage, cell adhesion, and cell differentiation.

Down Arrow Up Arrow
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
