Cloning Tools and Competent Cells

Single Step KRX Competent Cells

Efficient transformation and regulated protein expression. Ideal for rapidly generating new clones for recombinant protein expression.

pGEM® 3Zf+/- Vectors

Multi-purpose, blue/white screening vector with many unique restriction sites. Use as a standard cloning vector, for in vitro transcription, or for production of circular ssDNA.

T4 DNA Ligase

Blue/White cloning qualified. Use to join two strands of DNA between the 5´-phosphate and the 3´-hydroxyl groups of adjacent nucleotides in either sticky- or blunt-end configuration.
