我室从1956年起培育近交系小鼠。TA1系小鼠是我们建立的第一个近交系动物,现将其来源,建立经过。纯合程度及生物学特性报告如下。一、TA1系小鼠来源及建立经过TA1系小鼠来自本市家养的白化小鼠。自1956年夏季起按兄妹交配(b×s),至1962年母1系已达廿代命名为津白1系,代号为TA1系(Tientsin Albino 1 Strain)。为低 In my room since 1956 inbred mice. TA1 mice are the first inbred animals that we have established, and their origin is now established. The degree of homozygosity and biological characteristics are reported below. First, the origin of TA1 mice and the establishment of TA1-based mice from the city of domesticated albino mice. Since the summer of 1956, according to the siblings mating (b × s), until 1962 the mother 1 line has reached twenty generations named Jinbai 1 Department, codenamed TA1 line (Tientsin Albino 1 Strain).
