產(chǎn)品簡介:

Rapamycin(雷帕霉素),又稱為SirolimusAY22989,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與細胞內(nèi)受體FKBP-12結(jié)合形成復合物后,直接作用于mTOR中的FRBFKBP-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,從而加強與eIF4E的結(jié)合并使之失活。Rapamycin能夠阻斷蛋白合成,誘導細胞周期停滯在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細胞增殖治療器官或骨髓移植中發(fā)生的排斥反應,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,并根據(jù)自身實驗條件(如實驗目的,細胞種類,培養(yǎng)特性等)進行摸索和優(yōu)化?!?span>

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

(一)細胞實驗(體外研究)

Rapamycin顯著抑制T98GU87-MG細胞活力,100 nM Rapamycin作用于對Rapamycin敏感的U87-MGT98G細胞,通過抑制mTOR功能,而誘導細胞周期停在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]

體外研究:

細胞類型(Cell type):Human malignant glioma U87-MG and A172 cells

藥物配制(Preparation):Rapamycin was dissolved in DMSO to make 1mM stock solution and stored at -20℃.

實驗方法(Assay):Tumor cells were exposed to rapamycin (1, 10 or 100 nm) for 24 or 48 h. The cytotoxic effect of rapamycin was determined using a WST-1 cell proliferation assay.

體內(nèi)研究:

動物模型(Animal Model):Experimental osteoarthritis was induced in 2-month-old male C57Bl/6J mice

藥物配制(Preparation):Rapamycin was dissolved in DMSO at 25mg/ml and stored at -20℃. For injection, the stock solution was diluted in phosphate buffered saline (PBS).

注射劑量(Dosages):Mice received daily intraperitoneal injections of rapamycin at 1 mg/kg body weight/dose in a total injection volume of 0.3 ml for 10 weeks and control animals received the DMSO vehicle at 0.4% in a total injection volume of 0.3 ml.

給藥途徑(Administration):Intraperitoneal (i.p.) injection

體外研究:

細胞類型(Cell type):A172, U87, and U118 malignant glioma cell lines

藥物配制(Preparation):Rapamycin (NSC 226080) was dissolved in ethanol to yield a 5 mg/ml stock solution, which was stored at ?20°C.

實驗方法(Assay):Tumor cells were incubated with 0 or 100 nM rapamycin at 37°C for 72 h and then processed in a MTS assay.

體內(nèi)研究:

動物模型(Animal Model):8-10-week-old female athymic nude mice by s.c. injection of 2-5 million U87 cells

藥物配制(Preparation):For rapamycin injections, stock rapamycin was diluted first in sterile 10% PEG400/8% ethanol and then in an equal volume of sterile 10% Tween 80 for a final concentration of 20 μg rapamycin/100 μl. Rapamycin was delivered by i.p. injection, and the doses of rapamycin were calculated assuming that all mice weighed 20 g.
