About this protein | |
Name | Recombinant Human TSLP (Recombinant Human Thymic Stromal Lymphopoietin; rHuTSLP);重組人胸腺基質(zhì)淋巴細(xì)胞生成素 |
Synonyms | thymic stromal lymphopoietin |
Purity | >98% by SDS-PAGE and HPLC analyses. |
Biological Activity | Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using human IL-7Rα and human TSLP R co-transfected murine BaF3 pro-B cells is less than 0.3ng/ml, corresponding to a specific activity of >3.3×106IU/mg. |
Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation | Lyophilized from a 0.2μm filtered concentrated solution in 20mM PB, pH7.4, 150mM NaCl. |
Endotoxin | Less than 1EU/μg of rHuTSLP as determined by LAL method. |
Reconstitution | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions. |
Category | Cytokine |
Background | Thymic stromal lymphopoietin (TSLP) is a hemopoietic protein belonging to the cytokine family and is known to play an important role in the maturation of T cell populations through activation of antigen presenting cells. It is mainly expressed in a number of tissues including heart, liver and prostate. TSLP signals through a heterodimeric receptor complex composed of the thymic stromal lymphopoietin receptor and the IL-7R alpha chain. After binding STAT5 phosphorylation is induced resulting in the expression of downstream transcription factors. Like IL-7, TSLP induces phosphorylation of STAT3 and STAT5, but uses kinases other than the JAKs for activation. TSLP has the functions of enhancing the maturation of CD11c+ dendritic cells and inducing allergic inflammation by directly activating mast cells. It expression is linked to many disease states including asthma, inflammatory arthritis, atopic dermatitis, and eczema and other allergic states. But the factors inducing the activation of TSLP release are not clearly defined. Human TSLP shares approximately 43%a.a. sequence identity with mouse TSLP. |

保存條件:
???????-20℃或更低溫度保存,至少一年有效。由于蛋白的每次凍融均會(huì)引起部分失活,所以首次配制成相應(yīng)濃度的儲(chǔ)存液后(請(qǐng)根據(jù)產(chǎn)品簡介中Reconstitution一欄的信息配制儲(chǔ)存液),須分裝后-20℃或更低溫度凍存,以避免反復(fù)凍融。
注意事項(xiàng):
???????由于有些塑料管壁對(duì)某些蛋白有較強(qiáng)的吸附作用,溶液中的蛋白很容易粘附在管壁上,并且粘附后的蛋白很難與管壁分離。而載體蛋白(Carrier protein,如0.1% BSA等)的主要作用是預(yù)先封閉塑料管壁上的蛋白結(jié)合位點(diǎn),使細(xì)胞因子或重組蛋白不會(huì)粘附于管壁。所以一定要使用產(chǎn)品簡介中Reconstitution一欄的信息配制儲(chǔ)存液。
???????本產(chǎn)品僅限于專業(yè)人員的科學(xué)研究用,不得用于臨床診斷或治療,不得用于食品或藥品,不得存放于普通住宅內(nèi)。
???????為了您的安全和健康,請(qǐng)穿實(shí)驗(yàn)服并戴一次性手套操作。
