"Commercial scale" refers to gram scale production of a sialic acid in a single reaction. In preferred embodiments, commercial scale refers to production of greater than about 50, 75, 80, 90 or 100, 125, 150, 175, or 200 grams. An expression cassette can be constructed for production of more than one protein. If you have any inquiries concerning where and wa...
This was followed by the addition of neuraminidase solution or buffer control to each well and continued resistance measurement 4 (or more) h. AAV6 relies more on sialic acid or sialic acid-containing glycoproteins than AAV1 for cell entry and/or subsequent steps of infection. Neuraminidases are enzymes that cleave via hydrolysis α(2-3)-, α(2-6)-, and α(2-8)...

To assay for oxidoreductase activity, the purified recombinant proteins were incubated in 100-μl reactions at 37 °C overnight with 1 mg/ml 2,7-anhydro-Neu5Ac or Neu5Ac in 20 mm sodium phosphate buffer, pH 7.5, in the presence 500 μm NADH. The structure was acquired from a crystal grown in the JCSG Plus screen (100 mm sodium citrate, pH 5.5, 20% PEG 3000). Th...
