the expression of MUC6 mucin and co-expression of other secreted mucins
(MUC5AC and MUC2) in human gastric carcinomas.
J Histochem Cytochem. 2000 Mar;48(3):377-88.
Isotype : IgG1
Origin, source : Mice were immunised with a synthetic peptide (SFQTTTTYPTPSHPQTTLPC) conjugated with KLH correspoding to a part of the MUC6 tandem repeat. The fusion was perfomed with the NS-1 myeloma cells.The mouse sera was tested by ELISA, immunohistochemistry and Western blotting.
Specificity : The CLH5 monoclonal antibody reacts with the peptide and recognises mucin extracted from gastric mucosa on Western blotting. The antibody shows a stronger reactivity after deglycosylation.
Cross-reactivity : CLH5 shows no cross-reactivity with other mucin peptides on ELISA.
Immunoblotting : The CLH5 antibody gives a positive signal with mucin extracted from gastric mucosa, the signal is stronger after deglycosylation.
