Beta-Galactosidase Staining Kit 半乳糖苷酶染色套組

大腸桿菌中的LacZ基因是應用極廣的報告基因之一，被用來檢測表達載體介導的基因轉移效率，也用於基因啟動子研究。 LacZ編碼β-半乳糖苷酶，該物質非常穩定，能抵抗蛋白酶的水解，並且可以利用許多底物，包括X-gal。 X-Gal是β-半乳糖苷酶(β-galactosidase)的顯色底物，在β-半乳糖苷酶的催化下會產生藍色產物，所以可以輕易的檢測出LacZ基因的表達。

Kit Summary:

Features & Benefits:
• Simple and easy-to-use kit

Kit components:
• Fixative Solution (1X)

Description:
The LacZ gene from E. coli is one of the most commonly used reporter genes for testing the efficiency of expression vector mediated gene transfer and for studying the regulation of promoters of genes. The LacZ gene encodes the enzyme β-galactosidase, which is very stable, resistant to proteolytic degradation, can utilize a variety of substrates and can be easily assayed in situ. The β-Galactosidase staining kit utilizes X-gal as the substrate.

Storage Conditions:
-20°C
