Antibody Isotype & Constant-Region Assembly
Combine user-supplied VH/VL variable domains with explicit heavy- and light-chain constant-region references. Human and mouse references are retrieved through the existing Phase 44 UniProtKB-backed constant-region services.

Scientific guardrails
VH and VL are supplied by the researcher.
Heavy/light constant references remain explicit and provenance-linked.
Species/isotype does not determine variable-domain sequence.
No signal peptide is added automatically.
Strain/allotype-critical work requires exact allele verification.
An isotype-switched sequence is an architecture proposal. This page does not predict Fc function, glycosylation, expression, affinity, specificity or therapeutic behavior.
