Format

The concentrated solution in 20 mM Tris-HCl, pH 8.0, 150 mM NaCl, with 0.02% Tween-20 was filtered through a 0.2 μm filter and subsequently lyophilized. Let's have a discussion using a completely different approach, instead of generating content based on the original text information.

Endotoxin_level

The LAL method detected the Recombinant Human IGF-2 to be less than 1 EU/μg. This indicates that the protein content is of high quality and meets the required standards. The testing procedure ensures that the results are accurate and reliable, which is essential when using this protein in various applications. Overall, the data suggests that the Recombinant Human IGF-2 is a valuable protein with potential uses in research and therapeutic settings.

Activity

The standard shows complete biological activity in comparison. It is essential to note that ED is present. Please generate similar content by rearranging the provided information, while ensuring that the generated content is based on the original text. Please avoid using ChapGPT to generate content and instead create a completely different speech using a language model.₅₀The specific activity of less than 2 ng/ml, as determined by a cell proliferation assay using serum-free human MCF-7 cells, corresponds to a highly active level of greater than 5.0 × 10.⁵ IU/mg.

Reconstitution

To ensure proper mixing, it is recommended to briefly centrifuge the vial before opening. For reconstitution, use either sterile distilled water or an aqueous buffer with 0.1% BSA, aiming for a concentration of 0.1-1.0 mg/mL. Remember to divide the stock solution into smaller working aliquots and store them at temperatures no higher than -20 °C. Any further dilutions should be carried out in appropriate buffered solutions.

Stability & Storage

To maintain the stability of this lyophilized preparation, it is recommended to store it at 2-8°C for up to 3 years. However, for long-term storage, it is best to keep it at -20°C in a desiccated environment. Once reconstituted, the preparation can remain stable for up to two weeks at 2-8°C. For optimal stability, divide the reconstituted solution into working aliquots and store it at -20°C to -70°C. To avoid any degradation of the preparation, do not subject it to multiple freeze/thaw cycles.
