实验操作小课堂
RSL3产品问题解答
请问动物实验中,脑胶质瘤想要静脉注射,RSL3 这种脂溶性的小分子药如何给药?
10% DMSO +40% PEG300+5% Tween-80 +45% Saline 这个方案可以溶成 2mg/mL 的澄清溶液,正常小鼠可以给药。
请问 RSL3 的 HPLC 条件?
HPLC 方法如下:<br/>流动相A:纯水+0.07% TFA<br/>流动相B:纯乙腈<br/>流速 1.0ml/min<br/>温度 40℃<br/>梯度(B pump)<br/>0min 5%<br/>4.5min 95%<br/>5.3min 95%<br/>5.31min 5%<br/>8min stop
请问下 RSL3 这个激活剂做细胞实验和大鼠体内实验的浓度是多少? 有 RSL3 对软骨细胞或者滑膜细胞的浓度,对大鼠骨关节炎模型的用量吗?
可以参考以下文献:<br/>细胞实验:H-ferritin suppression and pronounced mitochondrial respiration make Hepatocellular Carcinoma cells sensitive to RSL3-induced ferroptosis;<br/>大鼠实验:Induction of ferroptosis promotes vascular smooth muscle cell phenotypic switching and aggravates neointimal hyperplasia in mice;<br/>滑膜细胞: Icariin enhances cell survival in lipopolysaccharide-induced synoviocytes by suppressing ferroptosis via the Xc-/GPX4 axis;<br/>软骨细胞: Theaflavin-3,3′-Digallate Inhibits Erastin-Induced Chondrocytes Ferroptosis via the Nrf2/GPX4 Signaling Pathway in Osteoarthritis。
常见问题解答
Tween-20 可以用 Tween-80 替代吗?
不建议使用 Tween-20。相较于 Tween-20,Tween-80 的耐受性更好,Tween-80已被用作评估实验药物和毒物的行为影响的工具,且没有明显的副作用。 参考文献:Castro CA, Hogan JB, Benson KA, Shehata CW, Landauer MR. Behavioral effects of vehicles: DMSO, ethanol, Tween-20, Tween-80, and emulphor-620. Pharmacol Biochem Behav. 1995 Apr;50(4):521-6.
如何选择合适的溶剂?
常用的溶剂包括DMSO、水、乙醇等。建议您根据抑制剂给出的溶解度参考,选择合适的溶剂。如果该抑制剂可以溶于DMSO,建议使用没有吸潮新开封的 DMSO,如果有潮气污染,很容易带来抑制剂降解或难溶的问题。如果该抑制剂可以溶于水,建议您根据实验类型选择无菌水、生理盐水、无菌 PBS 、培养基等作为溶剂。
PEG300 可以用 PEG400 替代吗?
PEG300 具有适度的粘稠度,有利于药物的溶解和给药过程,同时也能够提供良好的耐受性,不会对动物造成不良影响。PEG400 可以替代 PEG300。 PEG600 不是很建议,因为熔点接近常温。
抑制剂是否可以高温灭菌?
大部分产品均通过化学方法合成,反应条件一般在 50-80℃ 之间,因此不建议使用高温灭菌法进行灭菌,建议用 0.22 μm 滤膜过滤灭菌。
如何稀释工作液?
根据您的工作液浓度,计算母液所需要稀释的倍数和所需母液的体积。建议用水、生理盐水、PBS等溶剂进行稀释,如果是细胞实验,可以使用培养基。 取适当的溶剂缓慢加入到母液中,直到达到您的工作液浓度,可以通过涡旋或者移液枪轻轻吹打帮助混匀。 我们的化合物大部分是脂溶性的,所以在使用 PBS 或者培养基等稀释工作液的时候,会有沉淀析出,这些都是正常现象,大多时候可以通过超声完全溶解。 工作液建议现配现用!
