Description:DNA Polymerase I Holoenzyme, E. coli, 1 mg

Description: DNA polymerase I holoenzyme catalyzes primer extension of a double strand DNA template in the presence of dNTPs. This enzyme has 3'-5' exonuclease activity and 5'-3' proofreading exonuclease activity

Inexpensive: less expensive than New England Biolabs

Highly Purified: Greater than 98% purity as determined by SDS-PAGE gel analysis. Purity is suitable for all molecular biology applications. This product does not contain bovine serum albumin, or any other protein additives.

Supplied: DNA polymerase I holoenzyme is supplied in glycerol buffer at high concentration, usually 10 mg/ml or higher. Typical DNA polymerase reactions can be easily accomplished by using a 100 fold (or more) dilution of this enzyme preparation.

Quality Control: DNA polymerase I holoenzyme is fully quality control tested for polymerase activity, and for absence of nonspecific endonuclease and exonuclease contaminating activities. This enzyme prparation is free of contaminating DNA and RNA, and free of protein additives such as BSA.

Bulk Quantities: Bulk quantities from 100 mg to multiple grams are available at low cost. Please contact us for price and availability of bulk quantities.

Shipping: Standard shipping for T4 DNA ligase is Federal Express overnight delivery in wet ice.
