纯度: >95% by SDS-PAGE and HPLC analyses.

内毒素水平: Less than 1 EU/μg of rHBsAg-preS2 as determined by LAL method.

形态: Lyophilized from a 0.2 μm filtered concentrated solution in 20mM PB, pH 7.4, 50mM NaCl.

溶解方法: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at <-20°C. Further dilutions should be made in appropriate buffered solutions.

储存/保存方法: This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
