Are there reagents, enzymes, or toxins that bond proteins together?

Just heat them.

The classic example is a boiled egg:
- At room temperature, the proteins in the "white" of the egg form little balls, and they slide over each other easily, forming a viscous fluid.
- Heat it to 100C for 5 minutes, and the proteins denature, and form a tangled knot that is solid and doesn't flow
- Thus binding the proteins together

disulfide bonds are a good way to stick cystine-rich proteins together. first reduce them all to SH termination, then you might be able to oxidize them in a high enough concentration to have cross-linking between proteins. You might also use a bis-thiol linker.
