Monoclonal antibodies and their characteristics
| Antigen(s) | Clone(s)* | Isotype† | Cellular reactivity |
|---|---|---|---|
| *Sources: DAKO, Hamburg, Germany (CR3/43); Serotec, Oxford, UK (all others). | |||
| †Mouse antihuman antibodies throughout. | |||
| ‡Antibodies recognise the CD45 and CD45RB splicing variants. | |||
| §Antibody recognises a common αβ chain framework determinant. | |||
| ¶Antibody recognises a monomorphic epitope present on all TCR Cγ domains. | |||
