Associations of B2M with chemical compounds

  • During the final purification of beta 2M by CN reverse phase HPLC the mitogenic activity for bone cells separated from the beta 2M protein peak [11].
  • The ED50 of the bone-derived beta 2M (4,890 +/- 462 ng/ml) was several orders of magnitude (2 x 10(3) to 1.4 x 10(5) times) greater than the ED50 of simultaneously assayed purified growth factors and was no different from the ED50 of the crude EDTA matrix extract (3,350 +/- 890 ng/ml) [11].
  • Purified TGF beta, beta 2 m, and IGF I migrated as single bands on polyacrylamide gel electrophoresis with respective molecular masses of 24,000, 10,000, and 7,500 [13].
  • CA amyloid appeared to be potassium permanganate sensitive and tryptophan positive, and in this respect different from most other amyloid types except for AA and beta-2 microglobulin amyloid [14].
  • It was found that the method using the beta 2-M-free urine as a diluent was more accurate than using PBS [15].
 

Other interactions of B2M

  • A principal component of antibody transport is the neonatal receptor for the Fc portion of immunoglobulin, a heterodimer of a MHC-1 alpha-chain homolog ( FCGRT) and beta-2-microglobulin ( B2M) [8].
  • In conclusion, adult bone matrix, like fetal bone cultures, contains TGF beta, beta 2 m, and IGF I and these factors may play a role in adult skeletal remodeling [13].
  • BAMP is antigenically distinct from all adult serum proteins, free secretory component, beta 2-microglobulin, lactoferrin, alpha-lactalbumin, beta-lactoglobulin, and five different caseins [16].
  • In addition the EPO adsorptive rate, as well as that of beta 2-microglobulin (beta 2-MG), was greater with a PMMA membrane than with a PAN membrane [17].
