Abstract

Four new intra-H-2 recombinants were characterized serologically and functionally. In two of these recombinants, B10.ASR1 and B10.ASR7, crossing over occurred between the A alpha and E alpha subregions, very probably in E beta since most intra-I region recombinants thus far investigated at the DNA level appear to involve recombination within the E beta gene. In the other two recombinants, B10.ASR2 and B10.ARS8, crossing over occurred between the S and D subregions. B10.ASR2 and B10.ASR8, crossing over occurred between the S and D subregions. B10.ASR7, which is serologically indistinguishable from B10.BASR1 and B10.S(8R), slightly stimulates and strongly responds to both of these strains in MLR. The probable location of the B10.S(8R) stimulatory product is E beta. The H-2 composition of B10.ASR1 is closest to that of B10.S(9R) and B10.HTT; therefore, precise definition of the cross-over point at the DNA level will be of particular interest.

小鼠H-2复合体内重组的研究:IV.新的重组单倍型H-2t7、H-2t8、H-2as2和H-2as3的表征
对4个新的h -2重组蛋白进行了血清学和功能鉴定。在其中两个重组体中,B10。ASR1和B10。ASR7,交叉发生在A α和E α亚区之间,很可能发生在E β,因为迄今为止在DNA水平上研究的大多数i区重组似乎涉及E β基因内部的重组。在另外两个重组体中,B10。ASR2和B10。ARS8, S和D次区域之间发生交叉。B10。ASR2和B10。ASR8,在S和D亚区之间发生交叉。B10。ASR7,在血清学上与B10无法区分。在MLR中,BASR1和B10.S(8R)对这两种菌株有轻微的刺激和强烈的反应。B10.S(8R)刺激产物的可能位置是E β。B10的H-2组成。ASR1最接近B10.S(9R)和B10.HTT;因此,在DNA水平上精确定义交叉点将是特别有趣的。
