This page allows you to identify the subgroup of a human light or heavy chain. The code which does the actual assignments was kindly supplied by Sophie Deret ( ) and it normally features as part of her Subim program. (You can also download from bioinf.org.uk)
The method is described in Deret, S. et al (1995), SUBIM: a Program for Analysing the Kabat Database and Determining the Variability Subgroup of a new Immunoglobulin Sequence, Comput Appl Biosci, 11, 435-439.
