Anti-Human Kappa Light Chains Market to Reach USD 623 Million by 2034
Market OverviewThe Global Anti-Human Kappa Light Chains Market was valued at USD 197.4 million in 2024 and is projected to reach USD 623.1 million by 2034, growing at a compound annual growth rate (CAGR) of 12.2% over the forecast period.
Anti-human kappa light chain antibodies are widely used to detect free or bound kappa light chains, key components of immunoglobulin molecules. These reagents are instrumental in diagnosing plasma cell dyscrasias such as multiple myeloma, light chain amyloidosis, and B-cell lymphomas, and in quality control testing during monoclonal antibody production. As diagnostic labs and therapeutic developers ramp up research and clinical testing, the demand for accurate, high-affinity antibodies targeting light chains is rising substantially.
