生长分化因子8/肌肉抑制素抗体英文名称  Anti-GDF8 

中文名称  生长分化因子8/肌肉抑制素抗体 

别    名  MSTN; growth differntiation factor 8; GDF 8; Growth differentiation factor 8; Growth/Differentiation Factor 8; myostatin; GDF8_HUMAN. 

浓    度  1mg/1ml 

规 格  0.2ml/200μg     

纯化的抗体可通过不同的途径获取，有些生长分化因子8/肌肉抑制素抗体可通过下述方法制备或从商家购买。从商家购买的抗体，通常附有正确的储存方法。

1）工作液应在4℃下融化并存放，可能稳定达数月。

2）如果没有特殊原因而避免使用叠氮钠，亦可加入叠氮钠，浓度为0．02％。将纯化的抗体样本分装成合适的体积，于-20℃保存。

3）纯化的抗体溶液应以较高的浓度(如lmg／m1)在中性pH下保存。：常用的抗体储存浓度高达l0mg/ml。较低浓度的抗体冻存前应浓缩。所有标准的浓缩方法(如超滤法)，皆可使用。还有一个简单的方法是用蛋白A或蛋白G亲和柱来浓缩溶液。如果纯化的抗体不是用于标记，可将它们以较低浓度储存于加有1％BSA的溶液中。

4）经纯化制备的抗体在常用的缓冲液中是稳定的。其DH应保持在中性左右。如果pH在7-8之间，即使保存多年，对抗体也无损害。多数情况下，盐浓度适于保持在0-150mmol/L之间，但在长期存放的抗体中，盐溶液浓度高达500mmol/L时，对生长分化因子8/肌肉抑制素抗体能有损害。如果没有其他说明．律议用PBS或50mmol/LTris(DH8．0)溶液长期存放抗体。

生长分化因子8/肌肉抑制素抗体产品介绍 Myostatin (GDF8)is expressed uniquely in human skeletal muscle as a 12 kDa mature glycoprotein consisting of 113 amino acid residues and secreted into plasma. Myostatin is a member of the transforming growth factor beta superfamily of secreted growth and differentiation factors that is essential for proper regulation of skeletal muscle mass. Studies have shown that myostatin could play an important role in cardiac development and physiology.

Function : Acts specifically as a negative regulator of skeletal muscle growth.

Subunit : Homodimer; disulfide-linked (By similarity). Interacts with WFIKKN2, leading to inhibit its activity. Interacts with FST3.

Subcellular Location : Secreted. 

Tissue Specificity : Predominantly expressed in muscle. At hatching, expression is strongest in the skin epithelium, and is also found in the retina and brain. From day 28, expressed in skeletal muscle. In the adult, highest expression is seen in the gastrointestinal tract, brain, muscle, heart and testis. Also expressed in the adult pharynx, kidney, spleen, liver, gill, eyes, skin, swim bladder and ovary.

DISEASE : Defects in MSTN are the cause of muscle hypertrophy (MSLHP) [MIM:614160]. MSLHP is a condition characterized by increased muscle bulk and strength. Affected individuals are exceptionally strong.

Similarity : Belongs to the TGF-beta family. 

Database links : UniProtKB/Swiss-Prot: O14793.1

GDF-8又称MSTN,是转化生长因子超家族，也是近年来发现的一类重要的肌细胞生长调控因子，它通过抑制MyoD家族成员转录活性负向控制肌细胞的生长发育，它的表达量与肌肉重量的变化呈负相关。
