Quantitative isolation of mouse thymus leukemia antigen, TL. 1976

T H Stanton, and J C Bennett, and M Wolcott

This report describes the purification of TL from papain digests of a tumor line (ASL1) and of an established cell line (L251A). Through the use of gel filtration and ion-exchange chromatography, the TL was purified approximately 100-fold with respect to the original digest. It was noted that the TL isolated from ASL1 had a specific activity 1.4 times higher than that isolated from L251A. The reason for this anomaly is unexplained. However, this work indicates that classical methods of protein chemistry can be used in the purification of these membrane components which are present in only small amounts on the cell surface.

D009363	Neoplasm Proteins	Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm.	Proteins, Neoplasm
D010206	Papain	A proteolytic enzyme obtained from Carica papaya. It is also the name used for a purified mixture of papain and CHYMOPAPAIN that is used as a topical enzymatic debriding agent. EC 3.4.22.2.	Tromasin
