What is the best way to crosslink an antibody to magnetic beads...

The simplest way to do it is to buy NHS-activated magnetic beads for conjugation to lysines on your Ab. The downside is that the beads are not particular stable during storage unless free of moisture, but once conjugated the link to the antibody is irreversible. If you are not used to doing reactions, this is your best option I think, and there is a high chance of success

There are plenty of other chemistries too, and nearly all of them also create a bond between lysines and the bead. So the specifics of the linker between the bead and antibody may change, but otherwise the Ab is coupled through the same lysines. Don't bother with complex site-directed protocols; you resort to these approaches only if the simple methods don't work.
