Abatacept (CTLA4lg) is a soluble fusion protein consisting of the extracellular domain of human CTLA4 and a fragment of the Fc portion of human IgG1 (hinge and CH2 and 3 domains). It is a selective T-cell co-stimulation modulator and a protein drug for autoimmune diseases.

体内活性 | Abatacept reduces paw edema, and the SC Multiple-dose group shows significantly greater (tobs = 2.50) paw edema reduction compared with the IV dose group. Abatacept exhibits linear PK across the studied doses. The NCA clearance (CL) is 20.8 mL/day/kg, volume (Vss) is 146 mL/kg, and bioavailability (F) of the SC dose dosing is 57.7% [2]. Abatacept (oral; 10 mg/kg; every 2 days) reduces the proportion of activated T cells (CD44highCD62L–) and inhibits the up-regulation of ICOS and CD71 in homozygous DO11.10 RAG-2–/–BALB/c (H-2d/d) mice [3]. |
动物实验 | Animal Model: Male Lewis rats (6-9 weeks old) with weights of 150-175 g. Dosage: 10 mg/kg (i.v.), 20 mg/kg (s.c. single-dose), 20 mg/kg (SC Multiple-dose) on day 21 with 10 mg/kg SC doses on days 23, 25, 27, and 29. Administration: i.v. or s.c. [2] |

对于不同动物的给药剂量换算,您也可以参考 更多...
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。
