When our plasma cells start producing a single cancer-causing protein rather than an array of antibody-like proteins to protect us, it's one of two arms of the Y-shaped protein that's likely to blame.

A test that measures kappa immunoglobulin free light chains in cerebrospinal fluid (KCSF) is a valid option for diagnosing multiple sclerosis (MS), new research suggests. Results showed that compared ...

There are two different types of light chains, kappa and lambda, which are distinctive in their amino acid sequence. We normally make about twice as many kappa light chains as lambda, and while cancer ...

Therapy-related B-lymphoblastic leukemia (B-ALL) following treatment for multiple myeloma is a rare occurrence. Despite its rarity and the lack of recognition by the World Health Organization as a ...
