Cry proteins

Vaxjo ID 312       
Vaccine Adjuvant Name Cry proteins       
Adjuvant VO ID VO_0005270
Description Cry proteins are insecticidal proteins derived from Bacillus thuringiensis (Bt) which are expressed in genetically modified (GM) crops to impart insect resistance.       
Stage of Development Research       
Host Species for Testing Mouse       
Components Plant expression of Bacillus thuringiensis (Bt) crystal (Cry)       
Function Plant expression of Bacillus thuringiensis (Bt) crystal (Cry) insecticidal proteins have been the primary way to impart insect resistance in GM crops       
Safety The paper concludes that Cry proteins are deemed safe by regulatory agencies globally and are unlikely to function as adjuvants, based on critical review of published literature, history of safe use in foods, safety of Bt donor organisms, and pre-market safety assessments for GM crops.
