Product Name |
Taq DNA Polymerase |
Catalog Number |
EG-1030 |
Description |
Taq DNA Polymerase, a thermostable enzyme derived from the pol gene of Thermus aquaticus YT-1 expressed in Escherichia coli, catalyzes 5’ to 3’ DNA synthesis with no 3’ to 5’ proofreading activity, low 5’ to 3’ exonuclease activity, and deoxynucleotidyl transferase activity, resulting in 3’-dA overhangs on PCR products, with a molecular weight of 94 kDa. |
Features |
- Thermostable with a half-life exceeding 40 minutes at 95°C
- Generates PCR products with 3’-dA overhangs
- Purity >99% by SDS-PAGE
- No detectable Escherichia coli 16S rDNA contamination by RT-PCR
|
Applications |
- Routine PCR amplification of DNA fragments up to 5 kb
- TA cloning
|
Source |
Recombinant Escherichia coli expressing the Thermus aquaticus YT-1 pol gene |
