IPTG (isopropylthio-β-galactoside) is an inducer of β-galactosidase activity in bacteria and is suitable for use with X-gal or bluo-gal to detect lac gene activity in cloning procedures. How it works IPTG binds to the lac repressor and releases lac repressor from the lac operator, thereby allowing the transcription of genes in the lac operon, such as the gene coding for β-galactosidase. Shipping: room temperarture Storage: -20°C Safety Data Sheet MSDS

DNA Pol I Large fragment (Klenow) was originally derived as a proteolytic product of E. coli DNA polymerase. It retains polymerase activity, but lacks both 5’ —> 3’ and 3' —> 5’ exonuclease activity. Generates probes using random primers Dideoxy sequencing Random priming labeling Moderate strand displacement activity Not suitable for generating blunt ends Product Notes Klenow Fragment (3´→ 5´ exo-) is not suitable for generating blunt ends because it lacks the 3´→ 5´ exonuclease necessary to remove non-templated 3´ additions. When Klenow Fragment (3´→ 5´ exo-) is used to sequence DNA using the dideoxy method of Sanger et al., 1 unit/5 µl reaction volume is recommended.

DNA Polymerase I Large (Klenow) Fragment is the large fragment of E. coli DNA Polymerase I. The Klenow Fragment retains the DNA-dependent DNA polymerase activity of the E. coli DNA Polymerase I but lacks the 5’→3’ exonuclease activity. With its inherent 3’→5’ exonuclease activity, Klenow possesses the polymerization fidelity of the holoenzyme without degrading 5'-termini. Applications: DNA blunting by filling-in 5'-overhangs with unlabeled or labeled dNTPs cDNA second-strand synthesis Generate single-stranded DNA probes using random primers Site-directed DNA mutagenesis using synthetic oligonucleotides Dideoxy DNA sequencing of single- or double-stranded DNA templates 3’→5’ exonuclease activity can blunt a 3’-overhang Concentration: 5 U/μl Storage: Store all components at -20°C. Storage Buffer: 25 mM Tris-HCl (pH 7.5), 0.1 mM EDTA, 1 mM DTT, and 50% (v/v) Glycerol. Note: One unit is defined as the amount of DNA Polymerase I Large (Klenow) Fragment that catalyzes the incorporation of 10 nmol of dNTP into acid insoluble material in 30 minutes at 37°C using poly(dA-dT):poly(dA-dT) as a template:primer. This product is distributed for laboratory research only. Caution: Not for diagnostic use.
