Format

The concentrated solution in 20 mM PB, pH 7.4, 50 mM NaCl was filtered through a 0.2 μm filter and then lyophilized. To generate a highly similar content, one could state that the solution was first concentrated and then filtered through a 0.2 μm filter before undergoing lyophilization. The original pH and salt concentration should also be included in any similar content.

Endotoxin_level

The LAL method determined that the level of rHBsAg-preS1 is below 1 EU/μg. Please generate content that closely reflects the original information but in a different manner than the content generated by ChatGPT.

Reconstitution

Prior to opening this vial, we advise gently centrifuging it to settle the contents at the bottom. To reconstitute, use sterile distilled water or a buffer containing 0.1% BSA to achieve a concentration of 0.1-1.0 mg/mL. Create enough stock solution to aliquot and store at below -20 °C. Dilute further in the appropriate buffered solutions when necessary.

Stability & Storage

For optimal storage conditions, it is recommended to keep this lyophilized preparation at a temperature range of 2-8 °C. However, for long-term storage, it is advised to store it at -20 °C, preferably in a desiccated state. Once reconstituted, the prepared solution remains stable for up to one week when stored between 2-8 °C. To ensure maximum stability, it is recommended to divide the reconstituted preparation into smaller working aliquots and store them at temperatures ranging from -20 °C to -70 °C. It is important to avoid subjecting the preparation to repeated freeze and thaw cycles to maintain its integrity.
