Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
Storage & Shelf Life
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
-
Shipping
In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.

Protein Description
Cry2Aa is a crystal protein produced by the bacterium Bacillus thuringiensis (Bt), known for its insecticidal properties against various pests, particularly in the order Lepidoptera. The research surrounding Cry2Aa focuses on its potential application in sustainable agriculture, serving as a biological control agent to reduce reliance on chemical insecticides. Its mechanism of action involves the binding to specific receptors in the gut of susceptible insects, leading to cell disruption and ultimately, insect mortality. The increasing concern over pesticide resistance and environmental impacts has driven interest in exploring the efficacy and safety of Cry2Aa, particularly in genetically modified organisms (GMOs) that express this protein. Studies are being conducted to optimize its expression in plant systems, assess its impact on non-target organisms, and evaluate its effectiveness within integrated pest management strategies. By enhancing our understanding of Cry2Aa's properties and functions, researchers aim to develop innovative approaches to pest control that support agricultural productivity while minimizing ecological footprints.
