We stained cell lines with lectins that have been used to recognize the following three different epitopes: (i) WGA recognizes all sialic acids, (ii) MAA recognizes α2,3 sialic acid, and (iii) SNA recognizes α2,6 sialic acid. In this report, we demonstrate that AAV1 and AAV6 use both α2,3 and α2,6 N-linked sialic acids for binding and infection. To analyze if the sialylated receptors of AAV1 and AAV6 are glycoproteins or glycolipids, we treated Cos-7 and Pro-5 cells with 200 μg/ml proteinase K. Cell viability was assessed immediately after proteinase K treatment, and no cytotoxic effect was observed If you want to see more information in regards to sialic acid powder factory take a look at our own web site. .
