产品描述 Description
产品文档 Product Documents
Purity:>98%
Product Data
Purity
Greater than 98.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Source
Saccharomyces cerevisiae.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Shipping Condition
Shipped at Room temp.
Synonyms
Interferon alpha 2b; IFNA; INFA2; IFN-? 2b; MGC125764; MGC125765.
Amino Acid Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Cys-Asp-Leu-Pro-Gln.
Solubility
It is recommended to reconstitute the lyophilized glycosilated IFN alpha 2b in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized glycosilated IFN-a 2b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution IFN-alpha 2b should be stored at 4°C between 2-7 days and for future use below -18°C .For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Biological Activity
The specific activity as determined in a viral resistance assay was found to be no less than 300,000,000IU/mg.
Formulation
Lyophilized from a 0.2ж╠m filtered concentrated (1mg/ml) solution in PBS, pH-7.4.
