Purified human, rat or guinea-pig beta 2-microglobulin (beta 2m) was mixed with sera from guinea-pig, rat, mouse, rabbit, horse, goat, cow, rhesus monkey or man. The mixtures were incubated at 37 degrees C for various lengths of time. When the sera were separated by gel-chromatography on Sephadex G-200, beta 2m was traced not only in 'free' form but also in fractions with higher molecular weights. Evidence is presented suggesting that heterologous beta 2m binds to beta 2m-containing molecules in sera by exchange with the homologous counterpart.
将纯化的人、大鼠或豚鼠β2-微球蛋白（β2m）与豚鼠、大鼠、小鼠、兔、马、山羊、牛、恒河猴或人的血清混合。混合物在37℃孵育不同时间。当通过Sephadex G-200凝胶色谱分离血清时，β2m不仅以“游离”形式被检测到，还在高分子量组分中被检测到。有证据表明，异源β2m通过与同源对应物交换，与血清中含β2m的分子结合。
