A quick, clean and easy to use alternative to using a scalpel or razor blade for the extraction of DNA and RNA bands from agarose gels following gel electrophoresis.
Blue/white color selection is a routine technique employed by molecular biologists. This technique simplifies the differentiation between colonies/plaques that contain a cloning vector without an insert and those that contain a vector harboring an insert of interest.
Our Universal Transfection Reagent is a unique formulation of a proprietary polymer blend used for transient and stable transfection of nucleic acids into various eukaryotic cell lines and hard-to-transfect primary cells. This is a fast and easy protocol is compatible
CIP is used to remove 5’-phosphate groups from DNA, RNA and both ribo and deoxy-ribonucleoside triphosphates. Detailed protocol on how to dephosphorylate DNA.
Technical Article on competent cells. Transformation is a process by which some bacteria take up foreign genetic material (naked DNA) from the environment.

BL21(DE3) Electrocompetent Cells are provided in 25 μL aliquots, sufficient for one reaction. Transformation is carried out in a 0.1 cm gap cuvette. Optimal settings for electroporation are listed in the table below. Note that alternate settings result in transformation
Protein synthesis using cell-free protein synthesis reagent kit consists of three stages: preparation of transcription template, transcription and translation.
Transient co-transfection of plasmids is a method that is commonly employed for cellular protein-protein interaction studies, transcription factor studies, and gene knockdown studies using shRNA encoding plasmids.
Calcium phosphate transfection is a common method for the introduction of DNA into eukaryotic cells. This protocol can be optimized for use with a wide variety of cell types.
The cloning process requires the ligation of linear DNA into a cloning vector. This ability to join fragments of DNA through recombinant technology is essential for many basic experiments in biotechnology.
Method for reverse transcription of RNA into DNA. Uses a premixed reagent that contains reverse transcriptase, dNTPs, primers, RNase inhibitor and buffer. Fast generation of cDNA.
For best results, ligation reactions must be heat inactivated at 70º C for 15 minutes before transformation. Alternately, the reactions may be purified.
Cell preparation for transfection Plate cells approx. 24 hours before transfection making sure cells are at optimal concentration (70 – 90 % confluency).
