Innovative Research of America(IRA) 是一家致力研发于药物定量定时缓释系统的专业化公司，又称Matrix-Driven Delivery (MDD) 给药系统。该给药系统由一个可生物吸收的基质组成，含有定量可控的活性给药成分，可以以设定的剂量在一定时间范围内进行给药。

Since it is not easy to administer drugs and hormones orally to research animals, several delivery methods have been devised as alternatives.  However, most scientists continue to labor with unreliable injectables to conduct their research.

艾美捷科技代理Abliance品牌全系列产品

Abliance是一家法国的抗体制造商和服务提供商，由专家组成的团队，在细胞培养、蛋白质工程和质量控制方面拥有深厚专业知识，专注为体外诊断（IVD）及科研领域提供高合规性抗体解决方案，满足研究和诊断工业市场的抗体需求。

▍Abliance公司产品提供丰富可选择的抗体库

● Abliance的二抗产品为多克隆抗体，通过使用人或动物免疫球蛋白对实验动物（兔、山羊或绵羊）进行高效免疫后获得。收集的免疫血清除含有目标特异性抗体外，还包含非特异性抗体及血清杂蛋白。

● Globulins：经过系列非特异性纯化步骤（脱脂处理→硫酸铵沉淀→透析）后获得球蛋白组分，此中间产物适用于免疫沉淀技术。

● Affinity purified antibodies：随后通过亲和层析对抗体进行纯化，从而确保高特异性。此外，抗鼠/兔IgG（H+L）二抗需在装有人源IgA/IgG/IgM的凝胶层析柱上进行系统化吸附处理，确保其与人源IgA/IgG/IgM无交叉反应。

● Fragments：Abliance提供经酶切获得的F(ab')₂和Fab片段，适用于免疫组化/细胞学检测及流式细胞术等场景。相较于含Fc区的完整抗体，这些片段能显著降低非特异性结合。其更小的分子量可增强细胞和组织渗透性。

● Labeled antibodies：Abliance供应多样标记物复合体：球蛋白组分、纯化抗体及Fab/F(ab')₂片段，可与荧光染料（异硫氰酸荧光素）、酶类（过氧化物酶、碱性磷酸酶、β-半乳糖苷酶、葡萄糖氧化酶）及生物素进行偶联。
