Abstract

Antibodies with uniform properties may occur in rabbits after immunization with Group C streptococci. These precipitating antibodies possess specificity for the group-specific carbohydrate. Not uncommonly, their concentration is between 20 and 40 mg/ml of antiserum. Evidence for molecular uniformity in the case of one of these antibodies, described in detail here, includes: individual antigenic specificity; monodisperse distribution of the light chains by alkaline urea polyacrylamide disc electrophoresis; and a single amino acid in each of the first three N-terminal positions of the light chains. When the amino acid sequence of rabbit antibody b+ light chains (kappa type) are aligned against their human kappa counterparts, a definite homology is observed between the N-terminus of the human and the rabbit variable region.

摘要

用C组链球菌免疫兔子后,可能会产生具有均匀特性的抗体。这些沉淀抗体对群特异性碳水化合物具有特异性。它们的浓度通常在每毫升抗血清20至40毫克之间。这里详细描述的其中一种抗体的分子均匀性证据包括:个体抗原特异性;碱性尿素聚丙烯酰胺圆盘电泳显示轻链呈单分散分布;轻链前三个N端位置的每一个都只有一种氨基酸。当将兔抗体b +轻链(κ型)的氨基酸序列与人κ对应物进行比对时,在人和兔可变区的N端之间观察到明确的同源性。
