Three genes specified expressed in hybrids and one gene over-expressed in hybrid were found. By cloning, sequencing and BLAST analysis, one specific expression cDNA band was cytosolic isocitrate dehydrogenase gene, the other two were new genes which function were unknown, and the over-expressed cDNA band was proteosome subunit p112 gene.

发现了 3 个杂种鸡特异表达的基因和 1 个杂种鸡表达增强的基因，进一步克隆、测序和比对分析初步表明：杂种特异表达的 cDNA 片断分别为鸡细胞质异柠檬酸脱氢酶基因和 2 个未知功能的新基因；杂种表达增强的 cDNA 片断为鸡蛋白酶体亚基 p112 基因。

The compositions by weight percentage of the passivation solution are: 3.12 to 4.74 percent of EDTA, 2.60 to 3.95 percent of hydroxylamine sulfate, 0.52 to 2.37 percent of citric acids, 1.04 to 2.77 percent of sodium pyroborate, the balance being water.
