| 基本信息 | |
| 基因名 | |
| 别名 | Protein FAM19A4;Chemokine-like protein TAFA-4;TAFA4;family with sequence similarity 19 (chemokine (C-C motif)-like);member A4;FAM19A4;chemokine-like protein TAFA-4 |
| 外观(性状) | Lyophilized from a 0.2 μm filtered solution of 20mM PB,150mM NaCl, pH7.4. |
| 纯度 | ≥90% 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 | FAM19A4 is a secreted，12 kDa member of the FAM19/TAFA family of chemokine-like proteins.Like other members of the FAM19/TAFA family，with the exception of TAFA5，mature FAM19A4 contains 10 regularly spaced cysteine residues.The FAM19A4 proteins are predominantly expressed in specific regions of the brain and the biological functions of FAM19A4 family members remain to be determined，but there are a few tentative hypotheses.First，FAM19A4 may modulate immune responses in the CNS by functioning as brain specific chemokines，and may act with other chemokines to optimize the recruitment and activity of immune cells in the CNS.Second，FAM19A4 may represent a novel class of neurokines that act as regulators of immune nervous cells.And third，FAM19A4 may control axonal sprouting following brain injury. |

| 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
