pGEM® β-Gal Control DNA【子货号:L473A,包装:2 x 10μg,,运保温度:–20°C】
描述:
pGEM®β-Gal Control DNA(pGEM® β - 半乳糖苷酶对照DNA)包含E. coli 野生型lac Z 启动子下游的β - 半乳糖苷酶序列。该产品在E. coli S30 Extract System for Circular DNA 中做为阳性对照。野生型lacZ 启动子不能启动线性DNA 模板的转录。本产品以0.5mg/ml 浓度溶于TE buffer 中。
原厂资料:
pGEM® β-Gal Control DNA contains the coding sequence of β-galactosidase downstream of an E. coli wildtype lacZ promoter. pGEM® β-Gal Control DNA can be used as a positive control in the E. coli S30 Extract System for Circular DNA. The wildtype lacZ promoter is not efficient for initiating transcription from a linear DNA template. Supplied as a 0.5mg/ml solution in TE buffer.
