Materials Required

Before beginning the protocol, ensure the following materials are available:

• YQ015 Mouse mAb (Ab351123) – formulated in PBS
• Phosphate-buffered saline (PBS), pH 7.4
• Appropriate blocking buffer (e.g., 5% non-fat dry milk or 3% BSA in PBS)
• Secondary anti-mouse antibody conjugated to an appropriate reporter (HRP, fluorophore, etc.)
• Standard immunoassay consumables: microplates, membranes, or slides depending on application
• Centrifuge and microcentrifuge tubes
• Ice bucket or cooling block for sample handling

Note: Specific secondary antibodies and blocking reagents should be selected based on the intended application. Consult your assay format guidelines for further details.

Antibody Preparation and Dilution

YQ015 Mouse mAb is supplied pre-formulated in PBS and does not require reconstitution from a lyophilized state. Follow these steps for preparation:

1. Thaw: Allow the antibody vial to thaw slowly on ice at 4°C. Avoid thawing at room temperature to preserve antibody integrity.
2. Mix gently: Briefly and gently vortex or invert the vial to ensure homogeneity. Do not vigorously vortex, as this may denature the antibody.
3. Centrifuge: Spin briefly (1,000–2,000 × g, 30 seconds) to collect any liquid from the cap.
4. Dilution: Prepare working dilutions in PBS or assay-specific buffer. The optimal working concentration should be determined empirically for each application and experimental system.
5. Aliquot: To avoid repeated freeze-thaw cycles, prepare single-use aliquots and store at –20°C or –80°C as appropriate.

Flag: Specific recommended dilution ranges are not provided in the source material and must be confirmed with the manufacturer or by titration experiments.

Storage and Handling

Proper storage and handling of YQ015 Mouse mAb are essential to maintain antibody activity and lot-to-lot reproducibility:

• Short-term storage (up to 1 month): Store at 4°C. Keep the vial tightly sealed to prevent evaporation and contamination.
• Long-term storage: Store at –20°C or –80°C in single-use aliquots to avoid repeated freeze-thaw cycles, which can degrade antibody performance.
• Avoid: Exposure to light, repeated freeze-thaw, and temperature fluctuations.
• Buffer: The antibody is supplied in PBS only. If your assay requires a different buffer, perform buffer exchange using standard dialysis or spin-column methods.
• Sterility: Handle under aseptic conditions if the antibody is intended for cell-based assays to prevent microbial contamination.

Note: Always check the vial label and Certificate of Analysis (CoA) for lot-specific storage recommendations.
