Product Overview

Description

Intact Genomics 5-alpha chemically competent E. coli cells are suitable for high efficiency transformation in a wide variety of applications such as cloning and sub-cloning. ig™ 5-alpha chemically competent cells are at least twice the transformation efficiency of  the nearest competitor.

Quality Control

Transformation efficiency is tested by using the pUC19 control DNA supplied with the kit and using the high efficiency transformation protocol. Transformation efficiency should be greater than 1×109 CFU/µg pUC19 DNA. Untransformed cells are tested for appropriate antibiotic sensitivity.

General Guidelines

Follow these guidelines when using ig™ 5-alpha chemically competent cells.

  • Handle competent cells gently as they are highly sensitive to changes in temperature or mechanical lysis caused by pipetting.
  • Thaw competent cells on ice, and transform cells immediately following thawing. After adding DNA, mix by tapping the tube gently. Do not mix cells by pipetting or vortexing.
