The presence of specific binding of SEA with membranes of lymphocytes from rabbit thymus is established. Components of a glycolipid nature are absent in the composition of the receptor complex for SEA on T-lymphocytes. Suitable conditions for the solubilization of the receptor membrane fraction by Triton X-100 are described. The SEA-binding membrane fraction is isolated by means of an affinity-chromatography method. The main component of the fraction is a protein with molecular mass 42 kd. The isolated protein inhibits the specific binding of [125I] SEA on cell (T-lymphocytes) and subcell (membrane) levels.
已证实SEA与兔胸腺淋巴细胞的膜存在特异性结合。T淋巴细胞上SEA受体复合物的组成中不存在糖脂性质的成分。描述了用Triton X-100溶解受体膜部分的合适条件。通过亲和层析法分离SEA结合膜部分。该部分的主要成分是一种分子量为42 kd的蛋白质。分离出的蛋白质在细胞(T淋巴细胞)和亚细胞(膜)水平上抑制[125I] SEA的特异性结合。
