IFN-alpha 2b/IFNA2 Protein, Human, Recombinant

IFN-alpha 2b/IFNA2 Protein, Human, Recombinant

产品编号 TMPJ-00746
别名: 干扰素, IFNA2, Interferon α-2, Interferon α-A, Interferon Alpha-2, IFN-α-2, LeIF A, Interferon Alpha-A, IFN-Alpha-2, IFN α2b

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.

分子量 17 KDa, reducing conditions
内毒素 Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
缓冲液 Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.2.
复溶方法 Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. 
存储

Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.

运输方式

The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below.
