LA Taq DNA polymerase with GC buffers

TaKaRa LA Taq DNA Polymerase with GC Buffer has the Takara LA Taq DNA Polymerase blend for long and accurate PCR paired with GC-optimized buffers to power through difficult-to-amplify GC-rich sequences, including genomic DNA. The GC-optimized Buffers I and II are specifically designed to amplify GC-rich DNA templates (up to 73% GC content) or templates with a significant amount of secondary structure:

GC Buffer I is recommended for amplification of fragments that are ≥5 kb in length
GC Buffer II is recommended for fragments that are 2–3 kb in length

For all reactions, purified human genomic DNA (100 ng in a 50 µL reaction) was used as a template in reactions containing Takara LA Taq polymerase with either LA PCR Buffer II (lane 1), GC Buffer I (lane 2), or GC Buffer II (lane 3), or a competitor's high GC DNA polymerase kit (lane 4). The sizes of the amplified products were 262 bp (GC content 73%) and 358 bp (GC content 71.5%). Lane M contains a 100 bp ladder. Back RR02AG: TaKaRa LA Taq DNA Polymerase with GC Buffer

More Information

PCR products

PCR products generated with Takara LA Taq contain a mixture of 3'-A overhangs and blunt ends, which allows >80% cloning efficiency into T-vectors. However, the efficiency of cloning longer products (>5 kb) into T-vectors is quite low. It is also possible to clone the product in blunt-end vectors after blunting and phosphorylation of the end.

How the leopard lost its spots

Why do the offspring of some leopards hide their spots, resulting in black panthers? An international team of researchers focused on ASIP, a gene that causes dark coat coloration in other felines. Takara Bio's LA Taq with GC Buffer was used to sequence a tricky stretch of exon 4 in leopards and Asian golden cats, identifying SNPs associated with melanistic coat color. Scientists can now answer the curious question of how leopards produce panthers. That's Good Science!

"It works very well for long pcr and easy optimise conditions. I have used it extensively in amplifiying 4kb to 17kb."
—Praveen Hajeri, UNIVERSITY OF MINNESOTA

"I have purchased your LA Taq. I tried it with and without adding pfu. I was looking for more product per PCR reaction. I got ~2X the amount vs my old Taq in a side by side test. Thanks "
—Maureen Tarsio, RESEARCH FOUNDATION FOR THE STATE UNIVERSITY OF NEW YORK
