Introductory pSTBlue-1 AccepTor™ Vector Kit
The AccepTor™ Vector Cloning Kits are designed to simplify the PCR cloning process by using non-proofreading thermostable DNA polymerases (i.e. 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.
AccepTor Vectors are supplied in a ready-to-ligate format. Simply mix the vector with your PCR product, add Clonables™ 2X Ligation Premix (Cat No. 70573), and transform into NovaBlue Singles™ Competent Cells (Cat. No. 70181). The entire procedure, from PCR product to plating transformants, can be performed in as little as 40 minutes with minimal pipetting.
AccepTor Vector Kits are available in an introductory 10-reaction size as well as 20- and 40-reaction configurations. The AccepTor Vectors are also available separately without the ligation and transformation components. Also see pSTBlue-1 AccepTor Vector Giga Kit (Cat. No. 71228) for information on using higher-efficiency competent cells.
Two different vectors, pSTBlue-1 and pETBlue™-1, are available as AccepTor™ Vector kits. Each is carefully prepared and tested for optimal cloning efficiency and provides easy visualization of recombinants by blue/white screening using lacZ α-complementation. The pSTBlue-1 is a general purpose vector with dual opposed T7 and SP6 promoters, both with amp and kan resistance, and an array of flanking restriction sites. The pETBlue-1 vector is a novel plasmid specifically designed to enable high-level T7 RNA polymerase-driven expression of target genes, while providing the convenience of a blue/white screening method. Screening is independent of expression because the associated T7lac expression promoter is in an opposed orientation relative to the E. coli promoter. pETBlue-1 facilitates the expression of native unfused proteins and allows for convenient subcloning of target genes already fused to existing detection and purification tags. An EcoR V cloning site is appropriately spaced downstream of an E. coli ribosome binding site. Inserts must encode an ATG start codon at their 5′ end if expression is desired. The sequence is numbered from the first base of the T7 promoter sequence.
