Format

The solution was filtered through a 0.2 μm filter and lyophilized into a powder. The original solution was prepared using 20 mM PB at a pH of 6.0 and contained 150 mM NaCl. To create a similar content, one could simply rearrange the information provided while staying true to the original text.

Activity

The standard is fully biologically active. This ensures that the ED is also biologically active and equivalent to the standard.₅₀The specific activity of less than 40 ng/ml, as determined by a cell proliferation assay using serum-free human MCF-7 cells, indicates a high potency with a value greater than 2.5 × 10.⁴ IU/mg.

Reconstitution

Prior to opening, we suggest briefly centrifuging the vial to settle the contents at the bottom. Reconstitute to a concentration of 0.1-1.0 mg/mL in sterile distilled water or an aqueous buffer that contains 0.1% BSA. Create working aliquots from the stock solutions and store at ≤ -20 °C. Dilute further in appropriate buffered solutions. Ensure that the content is highly similar to the original text but using rearranged wording.

Stability & Storage

The lyophilized preparation can be stored at 2-8 °C, but for long-term storage, it is recommended to keep it at -20 °C in a desiccated condition. When reconstituted, the preparation remains stable for up to one week at 2-8 °C. To ensure maximum stability, it is advised to divide the reconstituted preparation into smaller aliquots and store them at temperatures ranging from -20 °C to -70 °C. It is important to avoid repeated freeze/thaw cycles to maintain the integrity of the preparation.
