Select-HA™:
Hyaluronic acid (HA) Oligo-HAs are purified single-size hyaluronic acid oligomers prepared by testicular
hyaluronidase digestion. Data sheets are provided for the absolute average molecular weight determination of each Select-HA™ as characterized by
SEC-MALLS (size exclusion chromatography multiple angle laser light scattering). All other
currently available commercial Hyaluronic Acid
preparations have much greater size heterogeneity and run as a smear, but any given Select-HA™ runs as a distinct band.

ORDERING DETAILS
Select-HA™ Ladder: We have assembled different mixtures of linear Select-HA™ polymers of very defined size ranges for
use as size standards on gels or other separation methods. The sizes (masses) of the Select-HA™ samples have been determined by SEC-MALLS.
Two ranges for higher (HiLadder) or lower molecular weight (LoLadder) HA are now available.
Tagged
Select-HA™: A fluorescent or biotinylated narrow-size distribution HA polymer with a single fluorescein or biotin group.
Mega-HA™ Ladder: We have compiled a mixture of streptavidin/biotin Select-HA™ complexes of very defined size ranges for
use as size standards on gels or other separation methods. The size (mass) of the starting Select-HA™ sample has been determined by SEC-MALLS
and the resulting complexes migrate on gels with linear correlation to the expected polymeris mass. The ladder contains the original size
material plus larger complexes that are 2 times, or 3 times, or 4 times the size of the starting Select-HA™ polymer.
Nano-HA™: A variety of different sizes of HA oligosaccharides are available from HA 4-24 (note: the product number signifies the
number of monosaccharides thus HA12 is twelve monosaccharides long).
