PrimeSTAR GXL DNA Polymerase

PrimeSTAR GXL polymerase is our most robust high-fidelity polymerase available for challenging targets (GC-rich sequences, long amplicons, excess template). It is a modified version of the PrimeSTAR HS enzyme that includes an elongation factor to provide unsurpassed processivity.

PrimeSTAR GXL polymerase is our most robust high-fidelity polymerase available for challenging targets (GC-rich sequences, excess template, long amplicons). It is a modified version of the PrimeSTAR HS enzyme that includes an elongation factor to provide unsurpassed processivity.

PrimeSTAR GXL DNA Polymerase provides efficient PCR amplification even for the toughest scenarios, including amplification of GC-rich targets, amplification in the presence of excess template that can contribute to nonspecific binding, and amplification of long products (up to 30 kb). The antibody-mediated hot-start feature enhances PCR specificity and sensitivity. PrimeSTAR GXL polymerase comes with separate tubes of 5X buffer and dNTP mixture.

1.02 | Quantifying population size by the hairs of the bears

Asian black bears live in the Himalayas, parts of Asia, and the Japanese islands Honshu and Shikoku. Related to now-extinct bear species and classified as vulnerable, Asian black bears are of keen interest to conservation biologists. But they're also aggressive, and researchers weren't eager to get up close and personal. So, how to estimate population size accurately while minimizing bear interaction? Hair traps and a sensitive PCR assay using PrimeSTAR GXL polymerase. That's Good Science!

Hard to clone >65% GC rich clones. This product also was great for challenging genotype PCR reactions. I will be using this for my point mutation PCR cloning."
—Blake Nichols, UNIV OF CALIF DAVIS

I tried different Taq to amplify a fragment with a high GC content (70%) and this is the only one that worked!"
—Tatiana Ruiz Larroya, ACTIVE MOTIF INC.

It is a great enzyme. I love it! It is very good on pcr out long fragments, and i have tried other enzymes which can not do as good as PrimeStar GXL DNA polymerase on long PCRs. My lab have purchased several packs for this good enzyme."
—Katherine Tao, UNIV OF UTAH
