About this protein
|
Name
|
Recombinant Human IL-19 (Recombinant Human Interleukin-19; rHuIL-19);重组人白细胞介素19
|
Synonyms
|
IL-10C; IL-19; interleukin 19; MDA1; melanoma differentiation associated protein-like protein; NG.1Melanoma differentiation-associated protein-like protein; ZMDA1interleukin-19
|
Purity
|
>95% 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-20Rα and human IL-20Rβ co-transfected murine BaF3 pro-B cells is less than 1.5ng/ml, corresponding to a specific activity of >6.7×105IU/mg.
|
Physical Appearance
|
Sterile Filtered White lyophilized (freeze-dried) powder.
|
Formulation
|
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4.
|
Endotoxin
|
Less than 1EU/μg of rHuIL-19 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 100mM HAC 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.

Background
|
Human Interleukin-19 (IL-19) is encoded by the IL19 gene, which is located on the chromosome 1. The protein belongs to the IL-10 family that includes IL-10, IL-20, IL-22, IL-24, and IL-26. As a monomer made of seven amphipathic helices, IL-19 has a helical bundle and shares the same cell surface receptor (IL-20R) with IL-20 and IL-24. It may play some important roles in inflammatory responses because it up-regulates IL-6 and TNF-alpha and induces apoptosis.

保存条件:
-20℃或更低温度保存,至少一年有效。由于蛋白的每次冻融均会引起部分失活,所以首次配制成相应浓度的储存液后(请根据产品简介中Reconstitution一栏的信息配制储存液),须分装后-20℃或更低温度冻存,以避免反复冻融。
注意事项:
由于有些塑料管壁对某些蛋白有较强的吸附作用,溶液中的蛋白很容易粘附在管壁上,并且粘附后的蛋白很难与管壁分离。而载体蛋白(Carrier protein,如0.1% BSA等)的主要作用是预先封闭塑料管壁上的蛋白结合位点,使细胞因子或重组蛋白不会粘附于管壁。所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。
本产品仅限于专业人员的科学研究用,不得用于临床诊断或治疗,不得用于食品或药品,不得存放于普通住宅内。
为了您的安全和健康,请穿实验服并戴一次性手套操作。
