| 别名 | WAP Four-Disulfide Core Domain Protein 2;Epididymal Secretory Protein E4;Major Epididymis-Specific Protein E4;Putative Protease Inhibitor WAP5;WFDC2;HE4;WAP5 |
| 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 | WAP Four-Disulfide Core Domain Protein 2 (WFDC2) is a 25 kDa secreted glycoprotein containing two WAP domains.Mature human WFDC2 is 94 amino acids (aa) in length.It contains two WAP domains that likely mediate antiprotease and/or antimicrobial activity (aa 31 - 73 and 74 - 123).There are four potential splice variants.One shows a deletion of aa 27-74，while three others show aa substitutions: 28 aa for aa 75-124，23 aa for aa 1 - 74，and 10 aa for aa 71-124.WFDC2 is a member of a family of stable 4-disulfide core proteins that are secreted at high levels.It is expressed by a wide variety of epithelial cells，including respiratory epithelium，salivary gland mucous cells，breast duct epithelium，distal tubule renal epithelium，and epididymal epithelium.WFDC2 may be a component of the innate immune defences of the lung，nasal and oral cavities and suggest that WFDC2 functions in concert with related WAP domain containing proteins in epithelial host defence.WFDC2 re-expression in lung carcinomas may prove to be associated with tumour type and should be studied in further detail.Mammary gland expression of tammar WFDC2 during the course of lactation showed WFDC2 was elevated during pregnancy，reduced in early lactation and absent in mid-late lactation.WFDC2 can undergo a complex series of alternative splicing events that can potentially yield five distinct WAP domain containing protein isoforms. |

| 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 ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
| 内毒素 | Less than 0.1 ng/ug(1 IEU/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
