| Description: | The Select-HA Mega Ladder is a mixture of biotin-Select HA molecules of defined sizes for use as size standards in gel electrophoresis or other separation methods. This ladder covers a range from 2 megadalton to 8 megadalton. Select-HA? is a hyaluronic acid (HA) preparation of uniform and narrow size distribution prepared by in vitro synthesis using recombinant Pasteurella multocida hyaluronan synthase1. HA is a high molecular weight anionic polysaccharide (1,000-10,000 kD) composed of repeating disaccharides and is one of several glycosaminoglycan components of the extracellular matrix of connective tissue. Various biological activities are influenced by the HA size or chain length; processes including proliferation, angiogenesis, inflammation, and binding appear to be differentially affected by high or low molecular weight HA. |
