产品描述 | Folinic acid (Leucovorin) is a biofolic acid that can be used in the treatment of methotrexate, often in combination with Methotrexate (MTX) to reduce MTX-induced toxicity, and can be used as an adjuvant treatment for colon cancer. |
体外活性 | Methotrexate (MTX) alone induces a concentration-dependent increase in the percentage of micronucleated binucleated cells (MNBN) and abnormal cells (Abs). As the concentration of MTX increases, the nuclear division index (NDI) decreases. Similarly, the mitotic index (MI) also decreases at all tested concentrations of MTX. The addition of 50 μg/mL folinic acid significantly reduces the % MNBN (40-68%) and % Abs (36-77%). In the presence of 5 μg/mL folinic acid, inhibitory effects are observed as well (MNBN from 12% to 54%, Abs from 20% to 61%)[2]. |
体内活性 | Treatment with folinic acid (7.0 mg/kg; intraperitoneal injection; every other day; for 3 weeks) appears to reverse the growth inhibition induced by Methotrexate (MTX) administration in young male Balb/c mice. Long-term MTX administration is known to inhibit skeletal growth in mice[1]. |

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。
