Variable Region Characteristics

Purpose: Variable Region Characteristics analyzes protein sequences for V1, V2, V3, V4, V5 and reports length, glycosolations, and net charge. For details, see the explanation.

Details: The tool accepts a set of aligned protein sequences in Fasta, IG, table, and other formats, along with an optional reference sequence.
