Albumin & Proteins
Serum albumin is the most abundant plasma protein and one of the most widely used reagents in life science research, diagnostics, and biopharmaceutical manufacturing. SeamlessBio supplies Bovine Serum Albumin (BSA) in multiple specialty grades, Human Serum Albumin (HSA), and recombinant Human Serum Albumin (rHSA) expressed in CHO cells — covering applications from assay blocking and cell culture supplementation to pharmaceutical formulation and diagnostic kit development.
