Have you ever encountered these problems when performing IP/Co-IP (immunoprecipitation/co-immunoprecipitation) experiments?
1. Cluttered WB Background-Antibody heavy chains (55kDa) and light chains (25kDa) interfere with the target band.
2. Excessive Incubation Time-Traditional Protein A/G requires overnight incubation, resulting in a lengthy experimental cycle.
3. Cumbersome Operation-Diverse reagents, complex configurations, and numerous steps.
4. Unstable Results-Large batch-to-batch variations and poor reproducibility.
AlpVHHs with its Nanoselector IP/Co-IP Kit series, brings you a brand-new solution, ending your troubles!
Why Choose AlpVHHs’ Nanoselector IP/Co-IP Kit?
1. Dual Version Design to Meet Different Experimental Needs
(1) Exgenous IP/Co-IP Kit:
High-performance nanobody magnetic beads with full tag coverage, including 21 common tags such as Flag, His, and GFP. Direct WB after IP, with no light or heavy chain interference throughout, resulting in cleaner IP/Co-IP data.
(2) Endogenous IP/Co-IP Kit:
Utilizes high-affinity nanobodies, specifically designed for Mouse/Rabbit IgG. Contains a dedicated secondary antibody to avoid light and heavy chains, perfectly solving the three major pain points of Protein A/G: serum IgG interference, affinity differences (e.g., low affinity of Protein A for mouse IgG1), and light and heavy chain contamination. IP/Co-IP results are purer and more reliable!
2. Four Major Advantages, Redefining IP/Co-IP Experimental Standards
● One Box All You Need-Ready to Use Out of the Box
Magnetic beads + a complete set of buffers (lysis buffer/wash buffer/elution buffer) + negative/positive controls; no additional reagents required.
● Stable Entry -pM-Level Ultra-High Affinity
VHH nanobodies are covalently coupled to magnetic beads, ensuring stable performance and impressive loading capacity for highly efficient protein enrichment.
● Fast Entry-Rapid Incubation
Incubation at 4℃ requires only 0.5-1 hour for rapid capture, say goodbye to overnight waiting!
● Easy Operation-Magnetic Separation
No centrifugation required, simple separation with a magnetic rack saves time and effort, reduces protein loss, and improves recovery rate.
