Expression Region: 1-633aa
Sequence Info: Full Length
Source: E.coli
Tag Info: N-terminal 6xHis-tagged
MW: 74.7 kDa
Alternative Name(s): 71KDA crystal protein;Crystaline entomocidal protoxinInsecticidal delta-endotoxin CryIIA(b)
Relevance: Promotes colloidosmotic lysis by binding to the midgut epithelial cells of lepidopteran (Manduca sexta) larvae.
Reference: Two highly related insecticidal crystal proteins of Bacillus thuringiensis subsp. kurstaki possess different host range specificities.Widner W.R., Whiteley H.R.J. Bacteriol. 171:965-974(1989)
Purity: Greater than 90% as determined by SDS-PAGE.
Storage Buffer: Tris-based buffer，50% glycerol
Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.
Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
