Reagents > VRDye™ 490 Donkey anti-Goat IgG Secondary Antibody,VRDye™ 490 驴抗山羊 IgG 二抗
Immunogen
Goat IgG
Purity and Specificity
The antibody was isolated from antisera by immunoaffinity chromatography using antigens coupled to agarose beads. Based on ELISA, this antibody reacts with heavy and light chains of goat IgG and sheep IgG. This antibody was tested by dot blot and/or solid phase adsorbed for minimal cross-reactivity with human, mouse, rabbit, rat, chicken, guinea pig, hamster, swine, and horse serum proteins but may cross-react with immunoglobulins from other species. The conjugate has been specifically tested and qualified for Western blot applications.
使用与琼脂糖珠偶联的抗原，通过免疫亲和层析从抗血清中分离抗体。 基于 ELISA，该抗体与山羊 IgG 和绵羊 IgG 的重链和轻链反应。 该抗体通过斑点印迹和/或固相吸附测试，与人、小鼠、兔、大鼠、鸡、豚鼠、仓鼠、猪和马血清蛋白的交叉反应最小，但可能与来自其他物种的免疫球蛋白交叉反应 . 该偶联物经过专门测试，可用于蛋白质印迹应用。
Applications
- Western blotting
Formulation
VRDye 490 secondary antibodies are supplied as purified immunoglobulin conjugates, lyophilized in phosphate-buffered saline, pH 7.4. Protect from light. Store at 4 °C before and after reconstitution.
Each vial contains 10 mg/mL BSA (free of IgG and protease) as a stabilizer and 0.01% sodium azide as a preservative, after reconstitution. Concentration is 1.0 mg/mL when reconstituted as directed. Refer to the pack insert for details on reconstitution.
VRDye 490 二抗以纯化的免疫球蛋白偶联物形式提供，在磷酸盐缓冲盐水中冻干，pH 7.4。 避光。 在重组之前和之后储存在 4°C。
复溶后，每瓶含有 10 mg/mL BSA（不含 IgG 和蛋白酶）作为稳定剂和 0.01% 叠氮化钠作为防腐剂。 按照指示重新配制时，浓度为 1.0 mg/mL。 有关重组的详细信息，请参阅包装插页。
