Aladdin IgG洗脱缓冲液 (10×),pH 2.7 是一款高效胺基酸性洗脱缓冲液,专为从Protein A、Protein G、Protein A/G及Protein L亲和介质中解离并回收抗体而设计。该产品以10倍浓缩液形式提供,可直接稀释使用,能在低pH条件下实现便捷高效抗体洗脱,同时与多种免疫球蛋白纯化系统广泛兼容。
主要特点
高效洗脱:在低pH条件下可有效从所有主要IgG结合蛋白上解离结合抗体。
即用型浓缩液:10倍浓缩配方经济节约且便于储存,仅需使用纯化水稀释即可获得1×工作液。
广泛兼容性:适用于单重及多重亲和纯化流程中的抗体洗脱。
性能稳定:预调至pH 2.7,确保在不同应用中获得重复性良好的洗脱效果。
应用灵活:同样适用于抗原-抗体或常规蛋白质相互作用研究。
应用场景
使用Protein A、G、A/G或L树脂进行IgG纯化时的抗体洗脱。
特别适合研发规模的免疫亲和纯化。
兼容手动与自动化色谱系统。
适用于大多数抗原-抗体亲和纯化装置的洗脱流程。
使用说明
将10×浓缩液按1:9比例用纯化水稀释,制备1×工作溶液。
完成结合与清洗步骤后,将1×洗脱缓冲液加入亲和层析柱或树脂。
收集洗脱组分并立即使用适宜中和缓冲液(如1 M Tris-HCl,pH 9.0)进行中和,以保持抗体活性。
为获得最佳效果,建议与Aladdin Protein A/G IgG结合缓冲液配套使用。
注意事项
避免抗体长时间暴露于低pH环境,以防蛋白变性。
洗脱组分需及时中和处理,以确保抗体获得最佳回收率与稳定性。
对于敏感抗体,建议选用Aladdin温和抗原/抗体洗脱缓冲液(近中性高盐配方)。
Aladdin IgG Elution Buffer (10×), pH 2.7, is a highly efficient, amine-based acidic elution buffer designed for the dissociation and recovery of antibodies from Protein A, Protein G, Protein A/G, and Protein L affinity supports. Supplied as a 10X concentrate, this ready-to-dilute formulation ensures convenient, high-yield antibody elution under low-pH conditions while maintaining compatibility with a wide range of immunoglobulin purification systems.
Key Features
High-Efficiency Elution: Effectively dissociates bound antibodies from all major IgG-binding proteins under low-pH conditions.
Ready-to-Dilute 10× Concentrate: Economical and space-saving; simply dilute with purified water to obtain 1× working solution.
Broad Compatibility: Suitable for eluting antibodies in both singleplex and multiplex affinity purification workflows.
Consistent Performance: Pre-adjusted to pH 2.7 to ensure reproducible elution profiles across applications.
Versatile Application: Also effective in antigen-antibody or general protein-protein interaction studies.
Applications
Antibody elution in IgG purification using Protein A, G, A/G, or L resins
Ideal for research and development-scale immunoaffinity purification
Compatible with manual and automated chromatography systems
Suitable for elution in most antigen-antibody affinity purification setups
Instructions for Use
Dilute the 10× concentrate 1:9 with purified water to obtain 1× working solution.
Apply the 1× elution buffer to the affinity column or resin after binding and washing steps.
Collect eluted fractions and neutralize immediately with a suitable neutralization buffer (e.g., 1 M Tris-HCl, pH 9.0) to preserve antibody activity.
For optimal results, use in combination with Aladdin’s Protein A/G IgG Binding Buffer.
Notes
Avoid prolonged exposure of antibodies to low-pH conditions to prevent denaturation.
Neutralize eluted fractions promptly for maximum antibody recovery and stability.
For sensitive antibodies, consider Aladdin’s Gentle Ag/Ab Elution Buffer (near-neutral, high-salt).
