Biotinylated Select-HA™ is the biotin version of the Select-HA™ which allows the researcher to immobilize or detect the Select-HA™ through the avidin-biotin interactions. A single biotin is conjugated at the reducing-end of each Select-HA™ molecule which results in a more homogeneous conjugate compared with biotinylation of the HA carboxyl groups which is variable in both loading and conjugate locations. In addition, the reducing-end conjugation provides advantage over the HA carboxyl group biotinylation by not masking the HA functional groups and allowing access to the entire HA polymers.
