Recombinant Vibrio cholerae serotype O1 CTXB protein, comprising amino-acids 22-124 and incorporating a C-terminal His-tag, produced in mammalian HEK293 cells. Cholera toxin subunit B (CTXB) has been used as a marker for neuronal cells due to its high affinity for the GM1 ganglioside cell surface receptor on these cells. CTXB has no toxic activity by itself, and can therefore be used in cell culture.
