We have been using alk. phosphatase-conjugated anti-tryptase from Chemicon
MAB 1222A.
This antibody works fine for cryostat sections (1/500, o.n. 4C, DAKO Fast
Red), and formalin-fixed and paraffin-embedded tissue sections after HIER
(1/500, o.n. 4C, DAKO Fast Red). Tonsil can be used as positive control

See for example: Kaartinen M, Van der Wal AC, Van der Loos CM, Piek JJ,
