NDT403-e X-Gal histochemistry
The £]-galactosidase gene is often used as a reporter gene, ¡§marker¡¨ that is widely used for analysis of mutationally altered genes as well as gene regulation. The expression of £]-galactosidase gene can be detected by histochemical staining of tissue sections or cells. The method is based upon the ability of £]-galactosidase to hydrolyze 5-bromo-4-chloro-3-indolyl-£]-D-galactopyranoside (X-Gal), resulting in a blue staining in the cells expressing £]-galactosidase1.

This service includes tissue preparation, sectioning, histochemical staining, counterstaining (optional), and coverslipping. As a result, your will receive X-Gal stained sections ready for microscopic observations.

Remarks:
¡P A quotation is required before placing an order.
¡P The investigator needs to provide unfixed and freshly frozen tissue.
¡P Please contact us for more information.
