Overview

This product is composed of Na₂HPO₄, NaH₂PO₄, KCl, and MgSO₄. It is a buffer at pH 7.0 and has been filter-sterilized. It can be used to prepare Z buffer/X-gal solution for detecting the LacZ reporter gene in the nuclear system AH109 yeast two-hybrid and the membrane system NMY51 yeast two-hybrid.

Z buffer provides a buffering environment for yeast X-gal chromogenic experiments, making yeast colonies develop clearer and more persistent color.

 

Instructions for Use (using a 5 mL system as an example):

Add 13.5 μL of 2-mercaptoethanol (Aladdin Catalog No.: M755744) and 83.5 μL of X-Gal solution (20 mg/mL) (Aladdin Catalog No.: X1520260) to 5 mL of Z buffer. The preparation can be scaled up proportionally according to the required amount.

 

Precautions:

1.Pay attention to aseptic operation to avoid microbial contamination.

2.This product is for research use only. Do not use it for pharmaceutical, clinical diagnostic or therapeutic, food, or cosmetic purposes.

3.For your safety and health, please wear a laboratory coat and disposable gloves and a mask during operation.
