Description of Rat BD-4
BD-4 Rat Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 41 amino acids and having a molecular mass of 4.4kDa.The BD-4 is purified by proprietary chromatographic techniques.
Biological Activity
Measured by its antimicrobial activity against E. coli. The ED50 for this effect is typically 5-50µg/ml.
Reconstitution
It is recommended to reconstitute the lyophilized BD-4 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized BD-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution BD-4 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please avoid repeated freeze-thaw cycles.
