產(chǎn)品信息

產(chǎn)品簡介：

Rapamycin（雷帕霉素），又稱為Sirolimus和AY22989，是一種抗真菌和免疫抑制劑，特異性抑制mTOR蛋白（IC50約為0.1 nM）。Rapamycin與細(xì)胞內(nèi)受體FKBP-12結(jié)合形成復(fù)合物后，直接作用于mTOR中的FRB（FKBP-12-rapamycin binding）結(jié)構(gòu)域從而抑制蛋白活性。Rapamycin選擇性抑制IL-2誘導(dǎo)的p70 S6激酶磷酸化與功能活化，也可以促使4E-BP1/PHAS1去磷酸，從而加強(qiáng)與eIF4E的結(jié)合并使之失活。Rapamycin能夠阻斷蛋白合成，誘導(dǎo)細(xì)胞周期停滯在G1期。不同于FK506和其他免疫抑制劑，Rapamycin以非凋亡的方式阻斷活化T細(xì)胞增殖治療器官或骨髓移植中發(fā)生的排斥反應(yīng)，比傳統(tǒng)治療方法副作用更少。

使用濃度

【具體使用濃度請參考相關(guān)文獻(xiàn)，并根據(jù)自身實驗條件（如實驗?zāi)康?，?xì)胞種類，培養(yǎng)特性等）進(jìn)行摸索和優(yōu)化。】

相關(guān)實驗（數(shù)據(jù)來自于公開發(fā)表的文獻(xiàn)，僅供參考）

（一）細(xì)胞實驗（體外研究）

Rapamycin顯著抑制T98G和U87-MG細(xì)胞活力，100 nM Rapamycin作用于對Rapamycin敏感的U87-MG和T98G細(xì)胞，通過抑制mTOR功能，而誘導(dǎo)細(xì)胞周期停在G1期。[3]

（二）動物實驗（體內(nèi)研究）

在體內(nèi)實驗中，給小鼠腹腔注射4 mg/kg Rapamycin，Rapamycin有效抑制VEGF-A誘導(dǎo)的急性血管通透性，并完全抑制myrAkt1轉(zhuǎn)基因小鼠中血管形成。[6]
