Product Overview and Target Biology

PAM Mouse mAb (catalog number Ab351023) is a mouse monoclonal antibody raised against peptidylglycine alpha-amidating monooxygenase (PAM), an enzyme critical for the post-translational amidation of neuropeptides and peptide hormones. PAM catalyzes the conversion of C-terminal glycine-extended peptide precursors into biologically active alpha-amidated products, a modification essential for the full biological activity of many signaling peptides including oxytocin, substance P, and calcitonin.

The antibody is formulated in phosphate-buffered saline (PBS) without additional stabilizers or preservatives, making it suitable for downstream conjugation or direct application in standard immunoassay formats. Researchers investigating neuropeptide processing, endocrine signaling, or PAM-related disease mechanisms will find this reagent a useful tool for detecting and characterizing PAM protein expression.

Recommended Applications and Usage Guidelines

PAM Mouse mAb is intended for use in standard immunological research applications. While specific validated applications should be confirmed with the most current product datasheet, monoclonal antibodies of this class are typically employed in the following assay formats:

• Western Blot (WB): Detection of PAM protein in cell or tissue lysates under denaturing conditions. Titrate antibody concentration empirically for optimal signal-to-noise ratio.
• Immunohistochemistry (IHC): Localization of PAM expression in fixed tissue sections. Antigen retrieval conditions should be optimized for the specific tissue type.
• Immunofluorescence (IF): Visualization of intracellular PAM distribution in cultured cells using appropriate secondary antibodies conjugated to fluorophores.
• Enzyme-Linked Immunosorbent Assay (ELISA): Quantitative or qualitative detection of PAM antigen in solution-phase samples.

Always consult the official product datasheet (absea#KC-1809) for validated application data, recommended dilution ranges, and positive control information before commencing experiments.

Storage, Handling, and Stability

Proper storage and handling of PAM Mouse mAb are essential to maintain antibody integrity and ensure reproducible experimental results. The following best-practice guidelines apply to PBS-formulated monoclonal antibodies:

• Short-term storage (up to 1 month): Store at 2–8 °C. Avoid repeated freeze-thaw cycles, which can denature antibody structure and reduce binding activity.
• Long-term storage: Aliquot upon receipt and store at −20 °C or −80 °C. Single-use aliquots minimize freeze-thaw degradation.
• Carrier protein addition: If the antibody is to be stored at low concentrations for extended periods, consider adding a carrier protein such as BSA (0.1–1% w/v) to reduce adsorptive losses; however, confirm compatibility with downstream applications before addition.
• Avoid: Exposure to repeated temperature fluctuations, direct light, and contamination from non-sterile pipettes or tubes.

Since the formulation is PBS only (absea#KC-1809), no sodium azide or glycerol is present. Researchers should handle accordingly and ensure the absence of preservatives is compatible with their assay system.

Quality Control and Experimental Considerations

To obtain reliable and reproducible data when using PAM Mouse mAb, researchers should observe the following quality control and experimental best practices:

• Positive and negative controls: Always include a validated positive control (cell line or tissue known to express PAM) and an appropriate negative control (isotype control mouse IgG at equivalent concentration) in each experiment.
• Lot-to-lot consistency: When transitioning between antibody lots, perform a parallel comparison to confirm equivalent performance before committing to large-scale or longitudinal studies.
• Secondary antibody compatibility: Use anti-mouse secondary antibodies that are validated for the specific detection format. Cross-adsorbed secondaries are recommended when working with tissues from mouse origin to minimize non-specific background.
• Antibody titration: Optimal working concentrations should be determined empirically for each application and sample type, as activity can vary between experimental systems.
• Sample preparation: Ensure consistent lysis conditions, protein quantification, and loading for Western blot analyses to allow meaningful comparison across samples.
