Human TNFSF11 / RANKL / CD254 Protein, His Tag, active trimer (MALS verified)

分子別名（Synonym）

RANKL,CD254,TRANCE,OPGL,ODF

表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）

Human TNFSF11 Protein, His Tag (RAL-H5240) is expressed from human 293 cells (HEK293). It contains AA Gly 64 - Asp 245 (Accession # AAC51762.1).

Predicted N-terminus: His

蛋白結(jié)構(gòu)（Molecular Characterization）

This protein carries a polyhistidine tag at the N-terminus.

The protein has a calculated MW of 22.4 kDa. The protein migrates as 27-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

內(nèi)毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

純度（Purity）

>90% as determined by SDS-PAGE.

制劑（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景（Background）

核因子κB配體受體激活劑（RANKL），也稱為腫瘤壞死因子配體超家族成員11（TNFSF11）、TNF相關(guān)活化誘導(dǎo)細(xì)胞因子（TRANCE）、骨保護(hù)素配體（OPGL）和破骨細(xì)胞分化因子（ODF），被稱為II型膜蛋白，是腫瘤壞死因子（TNF）超家族的成員。RANKL通過(guò)其刺激破骨細(xì)胞形成和活性的能力，是骨吸收和整體骨密度的關(guān)鍵介質(zhì)。一些研究結(jié)果還表明，一些癌癥細(xì)胞，特別是癌癥細(xì)胞，可以激活骨重塑的增加，并最終增加總的骨生成。骨重塑和骨生成的增加增加了骨轉(zhuǎn)移的整體生長(zhǎng)。骨重塑的總體控制是通過(guò)RANKL與其受體或其誘餌受體RANK和OPG的結(jié)合來(lái)調(diào)節(jié)的。
