产品名称：Recombinant Human Interferon α2B Variant (Arg46)/IFN-α2B

描述: Recombinant Human Interferon alpha-2b is produced by our E.coli expression system and the target gene encoding Cys24-Glu188 is expressed.

背景说明: At least 23 different variants of IFN-α are known. The individual proteins have molecular masses between 19-26 kDa and consist of proteins with lengths of 156-166 and 172 amino acids. All IFN-α subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN-α subtypes differ in their sequences by only one or two positions. Naturally occurring variants also include proteins that are truncated by 10 amino acids at the carboxyl-terminal end.

别名: Interferon Alpha-2, IFN-Alpha-2, Interferon Alpha-A, LeIF A, IFNA2

Accession: P01563

纯度: Greater than 95% as determined by reducing SDS-PAGE.

来源: Escherichia coli.

内毒素水平: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.

活性: Measured by a viral resistance assay using VSV-WISH cells. Specific Activity is greater than 1.0 x 10^8 IU/ mg

溶解方法: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

形态: Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.2.

储存/保存方法: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
