Previous work using spectrophotometric assays reported that E. In case you have virtually any issues regarding exactly where in addition to how you can work with manufacturer of sialic acid powder for food Ingredients, you are able to e-mail us with the internet site. coli YjhC showed a weak interaction with Neu5Ac, with an apparent Km of 68.8 mm (20). Here, we used ESI-MS to assess the activity of YjhC against 2,7-anhydro-Neu5Ac or Neu5Ac. The glycan array binding data provide independent support of AAV1 interaction with α2,3 and α2,6 trisaccharides.
