Bacterial Protein Expression Technology Platforms

BIC offers highly sophisticated bacterial protein expression technologies to provide products tailored to your needs.

codon optimization

Codon and mRNA structure optimization

Our in-house bioinformatics tool translates the same amino acid to multiple triplet codons, which contribute to protein expression by plotting and adjusting the codon usage frequency and opening stem-loops in the process of transcription and translation. Read More >

protein Aliquot and lyophilisation platform

Vector construction

Our professional teams can help you construct a customized vector tailored to your research requirement (often affected by upstream sequences and downstream applications).

protein refolding platform

Multiple purification methods

Nickel affinity purification is our preferred method. Ion exchange purification, size-exclusion chromatography, and hydrophobic chromatography are also available in our protein purification service. We can also provide favorable protocols to optimize your project process. Read More >

protein identification platform

Multi-channel protein refolding

We possess state-of-the-art protein refolding technologies, includingtraditional dialysis and dilution methods, as well as on-column refolding generally used in large-scale protein production.Using multi-well platestoexplore refolding conditions, our teams can find the most effectiveconditionsforobtaining stably and uniformly refolded proteins with good solubility.

protein purification platform

MALDI-TOF

We provide MALDI-TOF MS, one of the most useful attributes in protein identification, to accurately determine the molecular weight of your protein of interest.

protein sequencing platform

Protein N-terminal sequencing

Our highly sensitive N-terminal sequencing technology enables us to quickly determine cleavage sites and confirm the identity of purified protein samples.

Aliquot and lyophilisation

To increase the stability of expressed recombinant proteins and reduce shipping cost, we provide aliquoting and lyophilisation service for long-term storage of your products.
