FIELD: biotechnology.
SUBSTANCE: antigen-binding fragments (Fab) are described that selectively bind to botulinum neurotoxin C, in particular humanized Fab. Yeast cells producing the said humanized Fab are presented. A method for producing the described humanized Fab is proposed. A method for botulinum neurotoxin C detection and a kit for botulinum neurotoxin C detection is also proposed.
EFFECT: invention allows to obtain reagents for botulinum neurotoxin C detection, which have a high binding specificity to the said neurotoxin.
