Lyophilized Standard Mix - Human CA50. PN: B115602S. One vial containing lyophilized CA50.
Application: Optimal antibody pair and antigen standard for assaying human Human CA50. To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.
Storage: 2-8 C in the dark.
Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Cancer Antigen 50 (CA50 or CA-50) are proteins mainly found in gastrointestinal cancers (e.g. pancreatic, stomach, hepatic and colorectal cancers) but also sometimes in other malignant growths (endometrial cancers). The CA-50 antigens occur in the cell membrane in a lipid-bound form (as ganglioside) and in a form bound to a high molecular weight protein (as glycoprotein). The CA-50 antigens are released by the tumors into the blood stream.
