Recombinant Human Interferon alpha-2a is produced by our E.coli expression system and the target gene encoding Cys24-Glu188 is expressed.
| 基本信息 | |
| 基因名 | |
| 别名 | Interferon Alpha-2;IFN-Alpha-2;Interferon Alpha-A;LeIF A;IFNA2 |
| 外观(性状) | Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.2. |
| 纯度 | ≥95% as determined by reducing SDS-PAGE. |
| 储存条件 | 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. |
| 运输条件 | The product is shipped at 2-8°C temperature. Upon receipt, store it immediately at the temperature listed below. |
| 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 only differ in their sequences by one or two positions.Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxy-terminal end. |
| 来源 | E.coli |
| 溶剂 | 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 distilled water.Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
| 内毒素 | Less than 0.1 ng/ug(1 EU/ug)as determined by LAL test. |

文献和实验Secretion of Recombinant Human Insulin-Like Growth Factor I (IGF-I)
The development of efficient recombinant protein production processes can be a critical factor in whether or not a pharmaceutical therapeutic protein can enter human clinical trials and ultimately the marketplace. This is especially true
In this chapter we describe efficient procedures for the construction, expression and screening of comprehensive libraries of human Fab antibody fragments displayed on the surface of filamentous phage. Phagemid vectors are used for placing
我们知道，PeproTech的所有细胞因子和蛋白均为冻干粉，这使得运输非常便捷，只要常温即可。而且，细胞因子和蛋白冻干粉非常稳定，在-20℃或-80℃条件下可保存数年。冻干粉在使用前需进行溶解，然后以液体形式加到培养体系或注射入动物体内。溶解步骤非常关键，因溶解不好会导致细胞因子或蛋白的失活，这也是很多用户在实际使用中经常遇到的问题。 那么，应该如何进行正确的溶解呢？ 下面我们以Recombinant Human IL-4 (重组人IL-4，产品编号：200-04)的说明书为例
