Three novel molecular forms of biliary glycoprotein deduced from cDNA clones from a human leukocyte library.Kuroki M., Arakawa F., Matsuo Y., Oikawa S., Nakazato H., Matsuoka Y.Biochem. Biophys. Res. Commun. 176:578-585(1991)

Liquid or Lyophilized powder

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20C/-80C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Repeated freezing and thawing is not recommended. Store working aliquots at 4C for up to one week.

The predominant forms expressed by T cells are those containing a long cytoplasmic domain (PubMed:18424730). Expressed in granulocytes and lymphocytes. Leukocytes only express isoforms 6 and isoform 1 (PubMed:11994468).
