Beta-2 microglobulin - Wikipedia
β 2 microglobulin (B2M) is a component of MHC class I molecules. MHC class I molecules have α 1, α 2, and α 3 proteins which are present on all nucleated cells (excluding red blood cells). [5] [6] In humans, the β 2 microglobulin protein [7] is encoded by the B2M gene. [6] [8]

What is the Beta-2 Microglobulin Test for CLL? - HealthTree
2024年8月29日 · Beta-2 microglobulin (B2M) is a cell surface protein that checks for cancer cell growth. It’s known as a tumor marker; it indicates that the cell is inflamed or performing abnormally. It can be found in blood or urine, and its discovery can indicate different diseases. When CLL cells replicate, they release B2M into the blood.
Beta-2-microglobulin - Pathology Tests Explained
Beta-2-microglobulin (B2M) is a protein that is found on the surface of almost all cells in the body and is shed by cells into the blood, particularly by B lymphocytes and tumour cells. It is present in most body fluids and its level rises with conditions that increase cell production and/or destruction, or that activate the immune system.
