Immunoglobulins

Immunoglobulins used in immunization and diagnostic kits must offer high purity, low endotoxin levels, and strong batch-to-batch consistency—without these, assays become unstable and unpredictable. YBL’s immunogen-grade IgG Fc, IgA, and IgM are engineered to solve this exact challenge. With verified purity, excellent structural integrity, and superior reproducibility compared to typical market alternatives, our immunoglobulins give manufacturers the reliability they need for robust assay development and confident diagnostic performance.
