Hovenberg HW, Davies JR, Carlstedt I. Different mucins
are produced by the surface epithelium and the submucosa in human trachea:
identification of MUC5AC as a major mucin from the goblet cells.
Biochem J. 1996 Aug 15;318 ( Pt 1):319-24
Origin, source : Rabbits were immunised with a synthetic peptide coupled with a carrier, the KLH ( Keyhole limpet hemacyanin). The peptide of 12 amino acid (RNQDQQGPFKMC) is repeated at least twice in cysteine rich domains of the tandem repeat region of the MUC5AC mucin.
Specificity :The Lum5-1 polyclonal antibody reacts with the respiratory tract mucins extracted from chronic sputum and normal secretions.
Cross-reactivity : Lum5-1 does not react with the mucin MUC2, (either unreduced or reduced), but in London it was found to give a slightly positive signal with pooled fractions of mucin MUC5B (either unreduced or reduced), and MUC6 on ELISA plates. No cross reactivity was observed with blood group substances ( A, LEA, LEB, H) obtained from ovarian cyst fluid.
Binding Assays : The antiserum was tested on ELISA against respiratory tract mucins extracted from chronic sputum and normal secretions.
Immunoblotting : Lum5-1 antibody recognises the gel fraction (reduced or unreduced) and the soluble fraction (reduced) of induced sputum.

:
The Lum5-1 antibody works on ethanol fixed tissues and shows the same
pattern as anti-M1 MAbs (21M1 and 45M1) and all the other anti-M1 MAbs
(1-13M1, 2-11M1, 2-12M1,9-13M1, 58M1 see http://www.rangueil.inserm.fr/mucines/Antibody.htm
