Butylparaben (Butyl 4-hydroxybenzoate) 是一种标准化的化学过敏原,可增加组胺释放和细胞介导的免疫。
产品描述 | Butylparaben (Butyl 4-hydroxybenzoate) is a standardized chemical allergen, increasing histamine release, and cell-mediated immunity. |
体外活性 | 经过butylparaben处理后,Sertoli细胞中的vimentin丝状体受到破坏。Sertoli细胞的细胞骨架对butylparaben作出反应,表现为vimentin丝状体分布的显著崩解[1]。 |
体内活性 | Butylparaben 在体内诱导塞尔特精支细胞纤丝(vimentin filaments)的崩解[1]。断乳后哺乳动物暴露于Butylparaben 对睾丸素分泌以及雄性生殖系统功能产生不良影响[2]。 |
细胞实验 | Mixed cultures of Sertoli and spermatogenic cells are prepared from three-week-old SD rats. Single cells are obtained by gravity sedimentation and use of 50% trypsin-EDTA. Cells are finally suspended at a concentration of 1 × 108cell/ml and maintained for 24 h in Dulbecco’s modified Eagle medium supplemented with 100 U/ml penicillin, 100 μg/ml streptomycin, and 10% fetal bovineserum. Thereafter, cells are maintained in serum-freemedium, which is changed every 24 h. At 72 h, spermatogenic cells are removed by treatment with hypotonic Tris buffer (20 mMTris–HCl, pH 7.4) for 5 min. The Sertoli cell-enriched cultures obtained are then maintained in serum-free medium for 24 h before being reseeded onto chamber slides. The samples are cultured for a further 5 days. Subsequently, they are exposed to 0, 1, 100 and 1000 nmol/ml butylparaben for 6 and 24 h. Some slides are stained with 0.5% toluidine blue for light microscopic observations, whereas the rest are used for vimentin immuno-histochemical analysis. (Only for Reference) |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
