Recombinant Human Antibody (B20-4) is capable of binding to VEGF, expressed in HEK293 cells. Expressed as the combination of a heavy chain (HC) containing VH from antiVEGF mAb and the CH1-3 region of human IgG1 and a light chain (LC) encoding VL from antiVEGF mAb and CL of human kappa light chain. Exists as a disulfide-linked dimer of the HC and LC heterodimer under non-reducing conditions.

Custom chemical conjugation of Polyethylene Glycol (PEG) polymers to proteins to enhance their pharmacokinetic properties, including increased half-life and reduced immunogenicity.

DSL binds to (beta-1,4) linked N-acetylglucosamine oligomers, preferring chitobiose or chitotriose over single N-acetylglucosamine residues. Biotium offers DSL conjugated to biotin and a selection of 6 bright and photostable CF® Dyes.

A lectin labeled with our superior fluorescent CF® dyes is an effective and widely used cell surface stain for yeast, fungi, and mammalian cells.
