Then we made the probe with DIG using the cloning product of cashmere goat and Mongolia sheep,for studying the expression of BMP-2 in hair follicle of Arbas cashmere goat and Mongolia sheep by In situ hybrition.

• 将克隆得到的山羊及蒙古绵羊BMP-2基因片段经体外转录成用地高辛标记的RNA探针,利用原位杂交方法研究绒山羊BMP-2 mRNA在绒山羊55天,75天和115天胎儿皮肤,成年羊3月,5月和10月皮肤及蒙古羊BMP-2 mRNA在蒙古绵羊11月皮肤组织中的表达情况。
