CJC 1295   中文名称: CJC1-295

CJC-1295是一种基于30个氨基酸肽的药物，可刺激垂体释放生长激素（GH）。它在性能增强肽中是独一无二的，因为存在一个反应性马来酰亚胺丙酸基团，该基团将肽共价连接到血浆蛋白表面的游离硫醇上。一旦结合，CJC-1295在血液中的活性时间明显长于快速排泄的非结合肽药物。CJC-1295与血浆蛋白的结合阻止了基于自上而下质谱的肽筛选方案的检测，因为它有效地成为分子量不确定的大分子蛋白。使用针对CJC-1295肽的一对单克隆抗体，我们提出了一种免疫聚合酶链式反应（I-PCR）检测方法，能够检测浓度低至0.8 pg/mL的CJC-1295蛋白结合物。检测内源性马GHRH需要马血浆中CJC-1295的筛查阈值为50 pg/mL。该检测方法在控制CJC-1295非法使用方面的有效性在纯种赛马给药后的马血液样本中得到了证实[1]。

Background: Communal online folk pharmacology fuels the drive for short cuts in attaining muscle enhancement, fat loss, and youthful skin. Objectives: The study used "netnography" to explore female use of CJC-1295, a synthetic growth hormone analogue from the perspectives contained in Internet forum activity. Methods: A systematic Internet search was conducted using variation of the term "CJC-1295"; and combined with "forum." Ninety-six hits related to bodybuilding websites where CJC-1295 was mentioned. Following application of exclusion criteria to confine to female use and evidence of forum activity, 9 sites remained. These were searched internally for reference to CJC-1295. Twenty-three discussion threads relating to female use of CJC-1295 formed the end data set, and analyzed using the Empirical Phenomenological Psychological method. Results: Forum users appeared well versed and experienced in the poly use of performance and image drug supplementation. Choice to use CJC-1295 centered on weight loss, muscle enhancement, youthful skin, improved sleep, and injury healing. Concerns were described relating to female consequences of use given gender variations in growth hormone pulses affecting estimation of dosage, cycling, and long-term consequences. Conclusions: Public health interventions should consider female self-medicating use of synthetic growth hormone within a repertoire of product supplementation, and related adverse health consequences.[Subst Use Misuse . 2016 Jan 2;51(1):73-84]

请根据您的实验动物和给药方式选择适当的溶解配方/方案：
1、请先配制澄清的储备液(如：用DMSO配置50 或 100 mg/mL母液(储备液));
2、取适量母液，按从左到右的顺序依次添加助溶剂，澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明，并不一定代表此产品 的实际溶解配方):
10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀/澄清；向上述体系中加入50 μL Tween-80，混合均匀/澄清；然后继续加入450 μL ddH2O (或 saline)定容至 1 mL；
3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、 如产品在配制过程中出现沉淀/析出，可通过加热(≤50℃)或超声的方式助溶;
5、为保证最佳实验结果，工作液请现配现用！
6、如不确定怎么将母液配置成体内动物实验的工作液，请查看说明书或联系我们;
7、 以上所有助溶剂都可在 Invivochem.cn网站购买。
