Qiaexpress Type Iv Kit - Ni-nta Spin Columns (50) , His-tagged Protein Purification, Rapid Spin Column Assay

The 31314 Ni-NTA Spin Kit (50) by Qiagen is a complete solution for the rapid purification of His-tagged proteins under both native and denaturing conditions. This kit includes 50 Ni-NTA spin columns pre-packed with nickel-nitrilotriacetic acid (Ni-NTA) resin, along with optimized buffers for efficient protein binding, washing, and elution. Each column has a binding capacity of up to 300 g of His-tagged protein, making it ideal for small-scale purification, expression screening, and functional assays. The spin-column format enables fast and reproducible purification in under 30 minutes using standard centrifuges, eliminating the need for specialized equipment. With high specificity and minimal non-specific binding, this kit ensures excellent protein purity and yield. The Ni-NTA Spin Kit (50) is an ideal choice for researchers who require a simple, reliable, and efficient method for small-scale His-tagged protein purification in biochemical and structural studies.
