Explore the “Getting Started” and “Troubleshooting” sections for solutions to top inquiries and common problems. Browse through the “Guides and Tools” section to access comprehensive product-related support resources.
Getting Started
- How does affinity chromatography work?
- I see that you offer multiple immobilization resins for protein immobilization. Which one should I use?
- What is hybrid purification and when should it be used?
- What reagents do you recommend to prevent nonspecific binding besides detergents when using the ProBond™ System?
- What are fusion tags?
Troubleshooting
- I am using the ProBond™ Purification System and my protein is not eluting. What should I do?
- My native eluted fractions do not contain the His-tagged protein when using the ProBond™ System. Do you have any suggestions for me to try?
- I’m getting very low protein expression from after isolation using the ProBond™ System. Can you provide any suggestions?
- I am using the NativePure™ Affinity Purification System. Some of the recombinant protein is in the flow through and wash fractions. What should I do?
- My tag does not cleave. What do I do?
