产品描述 | cGAMP disodium is a cyclic dinucleotide (CDN) found in bacteria that acts as an endogenous second messenger affecting interferon production in response to cytoplasmic DNA. cGAMP disodium cascades signals from type I interferons and other immune mediators by activating interferon gene stimulator (STING). cGAMP disodium is a potent sublingual immune adjuvant that enables better immune function (serum anti-PA neutralization and airway secretions anti-PA SIgA response). |
体外活性 | cGAMP disodium directly activates mouse and human dendritic cells in in vitro experiments [1]. It promotes the antigen-specific proliferative capacity of mouse spleen cells [2]. Furthermore, cGAMP disodium induces the induction of antiviral state and the secretion of type I IFNs through activation of the endoplasmic reticulum (ER)-resident receptor STING [3]. cGAMP disodium causes fibroblasts from patients to exhibit increased transcription of IFNB1, which encodes interleukin-1 (IL1), interleukin-6 (IL6) or tumor necrosis factor (TNF) genes did not show a transcriptional increase [4]. |
体内活性 | The titers of OVA specific IgA, total IgG, IgG1 and IgG2c in the serum of female C57BL/6 (H-2b) mice were higher than those of OVA immunized mice after the injection of 5μg at 6-8 weeks of age. |

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。
