The enzyme selectively cleaves the μ heavy chain within the linker region between the CH2 and CH3 domains, enabling efficient fragmentation of IgM molecules while preserving antigen-binding activity.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThis recombinant preparation of IgM Scissors (Protease for IgM cleavage) cleaves IgM under controlled conditions for antibody fragment preparation. It is produced in E. coli and supplied at \u0026gt;90% as determined by SDS-PAGE. Typical use is generating defined antibody fragments for characterisation and bioanalytical workflows.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eExpression System\u003c\/th\u003e\n\u003ctd\u003eE. coli\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNature\u003c\/th\u003e\n\u003ctd\u003eRecombinant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eForm\u003c\/th\u003e\n\u003ctd\u003eLiquid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePurity\u003c\/th\u003e\n\u003ctd\u003e\u0026gt;90% as determined by SDS-PAGE.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePredicted Molecular Weight\u003c\/th\u003e\n\u003ctd\u003e38.81 kDa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFormulation\u003c\/th\u003e\n\u003ctd\u003ePBS pH 7.4, 50% glycerol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUnit Definition\u003c\/th\u003e\n\u003ctd\u003eOne unit (U) of IgM Scissors is defined as the amount of enzyme required to cleave 50 µg of IgM under standard conditions of 37°C for 3 hours.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApplications\u003c\/th\u003e\n\u003ctd\u003eFunctional\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStorage\u003c\/th\u003e\n\u003ctd\u003eUse a manual defrost freezer and avoid repeated freeze thaw cycles.
