If you’re looking to biotinylate an antibody, you’re in the right place. In this guide, we’ll take you through the process step by step, ensuring that you have all the information you need to do it successfully.
How to Biotinylate an Antibody
Biotinylating an antibody can be a tricky process, but by following these steps, you can make sure that it goes smoothly:
Purchase the necessary reagents: You’ll need to acquire the biotin reagents, such as NHS-LC-biotin and sulfo-NHS-LC-biotin, as well as the antibody you wish to biotinylate.
Prepare the buffer: Prepare a buffer suitable for antibody modification, such as Phosphate Buffered Saline (PBS).
Reaction mixture preparation: Prepare the reaction mixture by mixing the antibody with the biotin reagents in the buffer.
Incubation: Allow the antibody to incubate in the reaction mixture for the appropriate amount of time, typically an hour or more.
Purification: Finally, purify the biotinylated antibody using various methods like gel filtration or ultra-centrifugation.
By following these steps, you should have successfully biotinylated your antibody.
