IFN a 2b Human, Yeast
Interferon-Alpha 2b Human Recombinant, Yeast
Catalog No. CYT-460
Synonyms:
Interferon alpha 2b, IFNA, INFA2, IFN-α 2b, MGC125764, MGC125765.

Introduction:
IFN-alpha is produced by macrophages and has antiviral activities. Interferon stimulates the production of two enzymes: protein kinase and an oligoadenylate synthetase.

Description:
Interferon-alpha 2b Human Recombinant produced in yeast is a single, glycosylated, polypeptide chain containing 165 amino acids and having a molecular mass of approximately 19 kDa.
The Interferon-alpha 2b gene was obtained from human leukocytes.
The IFN-a 2b is purified by proprietary chromatographic techniques.

Source:
Saccharomyces cerevisiae

Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation:
Lyophilized from a 0.2μm filtered concentrated (1mg/ml) solution in PBS, pH-7.4.

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.

Purity:
Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

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

Biological Activity:
The specific activity as determined in a viral resistance assay was found to be no less than 3.0 x 108 IU/mg.

Protein content:
Protein quantitation was carried out by two independent methods:

1. UV spectroscopy at 280 nm using the absorbency value of 0.924 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).

2. Analysis by RP-HPLC, using a calibrated solution of IFN-a 2b as a Reference Standard.

Usage:
ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. They may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
