Question

What do lectin affinity columns attract?

1) Proteins

Answer 1

Lectins are glycoproteins so carbohydrates or a group of them, it depends on the lectin which can be very sensitive

From what I read I saw that it attracts carbohydrate molecules. So I believe the answer would be carbohydrates.
