The pSTBlue-1 AccepTor™ vector kits are designed to simplify the PCR cloning process by using non-proofreading thermostable DNA polymerases (eg. KOD XL polymerase and native and recombinant Taq polymerases), which leave single 3'-dA overhangs on the reaction products. The AccepTor™ vectors enable direct ligation by virtue of single 3'-dU overhangs that anneal efficiently with 3'-dA extensions on PCR products. The dU residues are converted to dT residues in vivo following transformation.

The One Step RT-PCR Master Mix Kit allows rapid, sensitive analysis of gene expression from tissues and cells. It can replace methods for detecting and quantifying gene expression such as Northern blots, in situ hybridisation, dot blots, S nuclease assays and conventional two step RT-PCR. The kit utilises recombinant Thermus thermophilus (rTth) DNA Polymerase, which acts as both a thermostable RNA dependent DNA polymerase and a DNA dependent DNA polymerase. The rTth DNA Polymerase is provided in a 2X master mix with an antibody for antibody-mediated hot start, optimised buffer, and ultrapure deoxynucleotides. Antibody-mediated Hot Start enhances specificity of both reverse transcription and PCR. The kit enables cDNA synthesis from input RNA followed by PCR amplification of the cDNA in a single reaction, with no additional hands-on requirement for buffer changes or adding reagents. Typically, detection of a specific transcript requires only 2 hours.
