The amino acid sequences of the lambda chains of two mouse immunoglobulins have been determined. No variations were found between these proteins. The results are compatible with earlier fingerprinting analysis of the two chains, where no differences in the tryptic peptides could be demonstrated. The lack of sequence variations could be the result either of a peculiarly restricted expression of the lambda variable-region genome in the BALB/c myelomas or a small number of germ-line genes involved in the biosynthesis of light chains of the lambda type.
已测定两种小鼠免疫球蛋白λ链的氨基酸序列。在这些蛋白质之间未发现差异。这些结果与早期对这两条链的指纹分析结果相符,在指纹分析中未发现胰蛋白酶肽段存在差异。序列缺乏变异可能是由于BALB/c骨髓瘤中λ可变区基因组的特殊受限表达,或者是参与λ型轻链生物合成的少数种系基因所致。
