What enzyme should be selected for the digestion of IgA1?

IgASAP Sub1 specifically targets IgA1 and exhibits a faster reaction time (1 hour) compared to IgASAP Sub1+2 (16-18 hours). The cleavage site of IgASAP Sub1+2 is located six amino acids above that of IgASAP Sub1, resulting in the absence of potentially O-glycosylated residues on the Fab fragments. This characteristic can be advantageous in certain cases.
