B2M/Beta-2-microglobulin Protein, Human (His)

Cat. No.: HY-P7625
Handling Instructions

B2M/Beta-2-microglobulin Protein, Human (His), a recombinant human Beta-2-microglobulin produced in E. coli, has a His tag. Beta-2-microglobulin acts as a modulator of lymphocyte surface and as a potential regulator of the immune system[1].

Beta 2-Microglobulin is a low molecular weight protein with sequence homology to immunoglobulins. Under normal conditions beta 2-microglobulin is synthesized and shed by many cells, particularly lymphocytes, and is detectable in the circulation of normal individuals. Because of its small size it is normally filtered readily at the glomerulus and is catabolized by proximal tubular cells of the kidney. Impaired renal function and hyperproduction of beta 2-microglobulin are both associated with increased serum levels[1].

  • Dilution Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
