  • a The data show the condition for finding a match of length ml1 in a sequence with a particular VH-JH length (gl) with an approximate error of ±0.3%. ml1 is the match length from the D segment and 5% and 1% represent the match length required for a 95% and a 99% probability that the match is not from random chance.
