MASP1 Protein, Human (HEK293, His)

MASP1 Protein, Human (HEK293, His) is a recombinant human Mannan-binding lectin serine protease 1 produced in HEK293 cells, with a His tag at the C-terminus. Mannan-binding lectin serine protease 1 is a serine protease associated with humoral pattern-recognition molecules^[1].

Mannan-binding lectin (MBL)-associated serine proteases (MASP-1, -2, and -3) are homologous modular proteases that each associate with MBL and L- and H-ficolins, which are oligomeric serum lectins involved in innate immunity. MASP-1 is a serine protease associated with humoral pattern-recognition molecules and is an abundant component of the lectin pathway of complement. MASP-1 can autoactivate^[1][2].
