About this Antibody
Name
Recombinant Human NRG1-β1, 177-241a.a. (Recombinant Human Neuregulin 1-β1 EGF-like domain, 177-241a.a.; rHuNRG1-β1, 177-241a.a.)；重组人神经调节蛋白1-β1，177-241a.a.
Synonyms
GGF; HGL; HRG; NDF; ARIA; GGF2; HRG1; HRGA; SMDF; MST131; MSTP131; NRG1-IT2
Purity
>97% 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 serum free human MCF-7 cells is less than 0.5ng/ml, corresponding to a specific activity of >2.0×106IU/mg.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered solution in 1X PBS, pH7.4, with 5% trehalose.
Endotoxin
Less than 0.1EU/μg of rHuNRG1-β1, 177-241a.a. 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.

Background
Neuregulin 1 (NRG1) is in humans encoded by the NRG1 gene. It is one of four proteins belonging to the neuregulin family that act on the EGFR family of receptor. Neuregulin 1 is produced in numerous isoforms by alternative splicing, which allows it to perform a wide variety of functions. All NRG1 isoforms contain an EGF like domain (α or β splice variant that differ in their C terminal region) that is required for their direct binding to the ErbB3 or ErbB4 receptor tyrosine kinases. NRG1 is necessary for cardiac development, structural maintenance, and functional integrity of the heart. NRG1 and its receptor family ErbB can play a beneficial role in the treatment of chronic heart failure (CHF) by promoting survival of cardiac myocytes, improving sarcomeric structure, balancing Ca2+homeostasis, and enhancing pumping function.

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**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**于专业人员的科学研究用，不得用于临床诊断或**，不得用于食品或药品，不得存放于普通住宅内。 为了您的**和健康，请穿实验服并戴一次性手套操作。
