MUC5AC Antibody

• Catalog Number: orb749375
• Category: Antibodies
• Description: This antibody recognizes the peptide core of gastric mucin M1 (>1,000kDa), now identified as Mucin-5AC or MUC5AC. The MUC5AC epitope is destroyed by beta-mercaptoethanol and proteases but not by periodate treatment. MUC5AC antibody reacts with the gastric epithelium of normal human gastrointestinal tract as well as with the precancerous and cancerous colon but not with normal adult colon. It also reacts with fetal colonic mucosa. Resurgence of gastric mucin reactivity during colonic carcinogenesis is due to re-expression of the peptide core of gastric (or fetal colonic) mucins.
• Species/Host: Mouse
• Clonality: Monoclonal

• Formula: 0.2 mg/ml in 1X PBS with 0.1 mg/ml BSA (US sourced) and 0.05% sodium azide
• Hazard Information: This MUC5AC antibody is available for research use only.
• Entrez: 4586
• Storage: Store the MUC5°C antibody at 2-8°C (with azide) or aliquot and store at -20°C or colder (without azide).
• Buffer/Preservatives: 0.2 mg/ml in 1X PBS with 0.1 mg/ml rAlbumin (US sourced) and 0.05% sodium azide
• Note: For research use only
• Application notes: The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the MUC5AC antibody to be titered up or down for optimal performance.1. Staining of formalin-fixed tissues requires boiling tissue sections in pH 9 10mM Tris with 1mM EDTA for 10-20 min followed by cooling at RT for 20 minutes.2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
• Expiration Date: 12 months from date of receipt.
