293/CHE-Fc cell RRID: CVCL_6352 WEB: https://www.atcc.org/Products/All/CRL-2368.aspx A 293-derived cell line that is stably transfected to secrete the chimeric protein (CHE-Fc), a recombinant soluble chirmeric protein useful as a probe to detect 9-O-Acetylated sialic acids. 293/CHE-Fc ATCC: CRL-2368 293/CHE-Fc was established by cotransfecting human embryonic 293 cell (ATCC CRL-1573) with the plasmid pCHE-Fc and a plasmid encoding Genetic (G418) resistance. The cell line is stably transfected to secrete the chimeric protein (CHE-Fc), a recombinant soluble chirmeric protein useful as a probe to detect 9-O-Acetylated sialic acids. CHE-Fc is a bifunctional molecule that can be used either to cleave acetyl groups at the ninth position of sialic acids or as a binding probe for 9-O-sialic acids. https://www.atcc.org/Products/All/CRL-2368.aspx WEB: http://web.expasy.org/cellosaurus/CVCL_6352 293-derived cell
