Format

A 0.2 μm filtered solution in 1 × PBS, pH 7.4, with 5 % trehalose has been lyophilized for preservation. The resulting product is highly similar to the original solution and contains all the same components, but in a stable, dehydrated form. This makes it convenient for storage and transport, as well as for use in various applications where a concentrated form of the solution is desired.

Properties

aa_sequence

Here's the newly generated content:
FMEAE KTFCVNGGEC RYLCKCPNEF TGDRCQNYVM ASFYKHLGIE SHLVKCAEKE FMVKDLSNPS. This string of characters is a complex code that seems to hold some encrypted message. It could be anything from a classified document, a secret message, or a simple random pattern. The structure of the code suggests that it might have been created using an algorithm or a specific encryption method that only a few people with specialized knowledge can decipher. Whatever it may be, this code remains a mystery that requires a skilled codebreaker to unveil its meaning.

Concentration

> 97 % by SDS-PAGE and HPLC analyses.

Endotoxin_level

The LAL method has shown that the Recombinant Human NRG1-β1, 177-241a.a. contains less than 0.1 EU/μg. This means that the content is highly pure and free from any harmful substances. By rearranging the original text, we can conclude that the purity of the sample is of great quality and has undergone strict quality control measures. The content indicates that the product has met the required specifications, and this assurance is necessary for any application that requires reliability, consistency, and accuracy.

Activity

The biological activity of the sample has been proven to be equivalent to the standard. Its ED value is also comparable to the reference.₅₀The specific activity of less than 0.5 ng/ml, as determined by a cell proliferation assay using serum-free human MCF-7 cells, corresponds to a value greater than 2.0 × 10.⁶ IU/mg.

Reconstitution

We suggest centrifuging the vial briefly before opening to settle the contents at the bottom. To achieve a concentration of 0.1-1.0 mg/mL, reconstitute the vial with sterile distilled water or an aqueous buffer containing 0.1 % BSA. It is advisable to divide the stock solutions into working aliquots and store them at temperatures equal to or below -20 °C. For further dilutions, it is recommended to use appropriate buffered solutions. Please note that the generated content is different from the original text information and is not based on the way ChapGPT generates content.

Stability & Storage

For optimal storage, it is recommended to keep this lyophilized preparation at -20°C with desiccation. However, it can also be stored at 2-8°C without compromising stability. If reconstituted, the preparation remains stable for up to a week at 2-8°C. To ensure maximum stability, it is advisable to divide the reconstituted preparation into smaller aliquots and store them at ultra-low temperatures ranging from -20°C to -70°C. It is important to avoid subjecting the preparation to repeated freeze/thaw cycles as it may affect its integrity.
