Protein Expression Products & Reviews

Three different strains that provide varying levels of expression control with T7 promoter-driven vectors, such as the pCAL and pET vectors.BL21 derivatives for tight expression control Express toxic proteins Use BL21, BL21-Gold or BL21-CodonPlus cells High-level protein expression Use for established expression constructs Economical alternative

The easiest of HPLC systems to operate, without compromising build quality.

BL21(DE3) is a chemically competent  E. coli  cell suitable for transformation and high level protein expression using a T7 RNA polymerase-IPTG induction system.

Detect low-abundant proteins at the femtogram/mL level with the sensitivity and speed of the SMCxPRO™ immunoassay system – a powerful, compact and affordably priced protein quantifier. Discovery depends on detection. When the success of your research requires finding and quantifying low-level proteins, you need equipment you can rely on to detect your target.  This compact, benchtop instrument will fit seamlessly into your…

Streptavidin Magnetic Beads are 1 µm superparamagnetic particles covalently coupled to a highly pure form of streptavidin. The beads can be used to capture biotin labeled substrates including antigens, antibodies and nucleic acids.

Maximum protein recovery

The TNT® Coupled Reticulocyte Lysate Systems offer researchers an alternative for eukaryotic cell-free protein expression: a single-tube, coupled transcription/translation system. The TNT® Lysate Systems greatly simplify the process and reduce the time required to obtain in vitro translation results.

High Yield Cell-Free Protein Expression System  

The Affinity protein expression and purification system provides a simple, gentle and effective method for high-level protein expression and purification. The complete system includes pCAL expression vectors containing a calmodulin-binding peptide tag and calmodulin affinity resin.

BL21-CodonPlus strains are engineered to contain extra copies of genes that encode the tRNAs that most frequently limit translation of heterologous proteins in E. coli. They are ideal for difficult protein expression, especially when codon bias is a problem.
