β 2 microglobulin also known as 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 (excludes red blood cells).. However, I've obtained copies of her initial labwork and am confused about the difference/correlation between beta globulin and beta-2 microglobulin. Her results thus far only list a value for beta globulin, which is 6.4 (normal range 0.5 -1.1). I'm not even sure of the units of measurement since they're not included with the report.. "2 Globulin Beta 1 Globulin Beta 2 Globulin Gamma Globulin M-Spike (or M protein , Monoclonal protein, etc.) The Beta 2 Glob you mention is probably the Beta 2 Globulin that is usually reported in these sorts of tests.. Patologie che presentano gammaglobuline alte. Vediamo adesso nello specifico alcune delle più comuni malattie che determinano l’aumento delle gammaglobuline e di altri parametri. Malattie del fegato.. In order of decreasing electrophoretic mobility these fractions are the alpha 1-, alpha 2-, beta 1-, and beta 2-globulins, and the gamma globulins. The globulins include carrier proteins, which transport specific substances; acute phase reactants, which are involved in the inflammatory process; coagulation factors; complement components; and immunoglobulins.. Other articles where Beta globulin is discussed: globulin: …of globulin have been identified—alpha, beta, and gamma. Alpha and beta globulins are transport proteins, serve as substrates upon which other substances are formed, and perform other diverse functions. Gamma globulins have a vital role in natural and acquired immunity to infection..
