Number of kappa light chains
How many kappa light chains are there?
Not too many people know that there are two types of light chain in humans (as in other mammals: kappa (?) chain and lambda (?) chain. Keep in mind that each immunoglobulin molecule consists of two identical heavy chains and two identical light chains. The main idea is that there are two types of light chains designated as kappa and lambda. Moreover, the gene rearrangement process that generates the immunoglobulin molecule results in either a productive kappa gene or a productive lambda gene.
