Hyaluronic acid (HA) can be obtained from various sources, for example rooster combs or Streptococcus equi. We can supply derivatives of either of these qualities labelled with tetramethylrhodamine (T-HA). All batches are checked for molecular weight, degree of substitution, loss on drying and free TRITC. TdB Labs can produce T-HA with a molecular weight of approximately 1.5 MDa. T-HA is supplied as a pink powder.

Hyaluronic acid is a polysaccharide composed of alternating β(1-3) glucuronide and β(1-4) glucosaminide units derived from Streptococcus equi. The hyaluronic acid is labelled with amino-tetramethylrhodamine. The degree of substitution lies between 0.001 and 0.008. The labelling procedures do not lead to depolymerisation of the HA.
T-HA has an excitation maximum at 552 nm and an emission maximum at 576 nm.
Storage and stability
T-HA is stable for more than 6 years when stored dry in well-sealed containers.
