Q
What kind of protein expression systems have strong yao creatures?
Strong group biological technology co., LTD has successfully built a complete variety of protein expression technology platforms: including the original expression and purification of nucleoprotein, yeast protein expression and purification, insect cell protein expression and purification, mammalian cell protein expression and purification.
Q
How to choose the suitable protein expression systems?
According to the customer sources of protein (bacteria, animals, or other) and purified protein purpose is different, choose a different protein expression system. If you don't know how to choose, please consult the online customer service, we will recommend suitable expression system for you with all sincerity.
Q
How to define the protein service and long chain peptide service?
< 50 aa generally do peptide synthesis, > 50 aa peptide synthesis difficulties can try to express.
Q
What can affect gene synthesis and the expression of cost?
Gene synthesis cost depends on the length and complexity. Protein expression (production) costs mainly by the expression system, quality and purity of target protein, and other special requirements, such as tag removal and endotoxin level control, special labels, etc.
Q
Protein expression in the process, some impurities?
Impurities are mostly cells or substances in the culture medium, can remove by chromatography technology.
Q
How to determine the protein purity and quality?
Protein purity detection: a. sds-page and HPLC, c. b. argentation and defaults to using sds-page. Protein concentration detection: a. Bradford protein assay; B. BCA protein analysis method; Default to Bradford, if use BCA impact buffer composition; Antibodies are A280 detection.
