Uniprot Accesion Number O88514
Amino Acid SequenceQSINNPITCL TKGGVCWGPC TGGFRQIGTC GLPRVRCCKK K.
Source Escherichia Coli.
Physical Appearance and 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 prevent freeze-thaw cycles.
Formulation and Purity BD-4 protein was lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4. Greater than 97.0% as determined by SDS-PAGE.
Application
Solubility 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.
Biological Activity Measured by its antimicrobial activity against E. coli. The ED50 for this effect is typically 5-50µg/ml.
Shipping Format and Condition Lyophilized powder at room temperature.
