| 基本信息 | |
| 基因名 | |
| 别名 | Leukocyte-Associated Immunoglobulin-Like Receptor 1;LAIR-1;hLAIR1;CD305;LAIR1 |
| 中文名称 | Recombinant Human LAIR1/CD305 |
| 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 | Leukocyte-Associated Immunoglobulin-Like Receptor 1 (LAIR1) is a single-pass type I membrane protein.LAIR1 expressed on the majority of peripheral mononuclear cells，including natural killer (NK) cells，T-cells，B-cells，monocytes，and dendritic cells，highly in naive T-cells and B-cells.As an inhibitory receptor，LAIR1 plays a constitutive negative regulatory role on cytolytic function of natural killer (NK) cells，B-cells and T-cells.Activation by Tyr phosphorylation results in recruitment and activation of the phosphatases PTPN6 and PTPN11.It also reduces the increase of intracellular calcium evoked by B-cell receptor ligation.LAIR1 plays inhibitory role independently of SH2-containing phosphatases and modulates cytokine production in CD4+ T-cells.It down-regulates IL2 and IFNG production while inducing secretion of transforming growth factor beta，also down-regulates IgG and IgE production in B-cells as well as IL8，IL10 and TNF secretion.LAIR1 inhibits the differentiation of peripheral blood precursors towards dendritic cells.It also restrains proliferation and induces apoptosis in myeloid leukemia cell lines as well as prevents nuclear translocation of NF-kappa-B p65 subunit/RELA and phosphorylation of I-kappa-B alpha/CHUK in these cells. |

| 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
