Overview of PLS1 and Antibody Specifications

PLS1 (Plastin-1), also known as I-Plastin, is an actin-bundling protein that belongs to the plastin family. It plays important roles in cytoskeletal organization and is expressed in a tissue-restricted manner, with notable expression in the intestinal epithelium and inner ear hair cells. Research into PLS1 function has implications for understanding cell motility, morphology, and associated pathophysiological processes.

The PLS1 Mouse mAb (SKU: Ab351035) is a mouse-derived monoclonal antibody raised against the PLS1 protein. It is formulated in PBS (Phosphate-Buffered Saline) without additional stabilizers listed, and carries the reference code absea#KC-33512. As a monoclonal antibody, it offers high specificity and batch-to-batch consistency, making it suitable for reproducible experimental outcomes.

Storage, Handling, and Reconstitution

Storage: Upon receipt, store the PLS1 Mouse mAb at -20°C for long-term storage. For short-term use within one to two weeks, the antibody may be stored at 4°C. Repeated freeze-thaw cycles should be avoided, as they can compromise antibody integrity and performance. Aliquoting the antibody upon first use is strongly recommended.

Handling: Keep the antibody on ice during experiments. Avoid prolonged exposure to light and ensure the vial is tightly capped when not in use. As the formulation is PBS-based, no reconstitution step is required unless the product is supplied in lyophilized form — confirm the physical state of the product upon receipt.

Note: Always centrifuge the vial briefly before opening to collect any residual material from the cap or sides of the tube.

Recommended Protocol and Dilution Guidelines

The following general protocol steps apply to common immunoassay applications. Optimal working dilutions should be determined empirically by the end user for each specific application and sample type.

• Western Blot (WB): A starting dilution range of 1:500 to 1:2000 is typical for monoclonal antibodies in WB. Prepare cell or tissue lysates under denaturing conditions (SDS-PAGE). After transfer, block the membrane with 5% non-fat dry milk or BSA in TBST for 1 hour at room temperature. Incubate with PLS1 Mouse mAb overnight at 4°C. Wash three times with TBST and incubate with appropriate anti-mouse HRP-conjugated secondary antibody.
• Immunofluorescence (IF) / Immunohistochemistry (IHC): Dilutions of 1:50 to 1:200 are generally recommended as starting points. Perform antigen retrieval as appropriate for the tissue type. Block with serum-based blocking solution. Incubate primary antibody overnight at 4°C.
• ELISA: Coat the plate with antigen and block. Apply primary antibody at an appropriate dilution and incubate. Use an anti-mouse secondary antibody conjugated to HRP for detection.

Note: Specific validated dilutions and confirmed applications for Ab351035 are not detailed in the current source material. Users should consult the product datasheet or contact Aladdin Scientific technical support for confirmed application data.

Troubleshooting Common Issues

The following troubleshooting guidance applies to general monoclonal antibody usage and may assist researchers encountering issues with PLS1 Mouse mAb:

• No Signal / Weak Signal: Verify that the antibody has been stored correctly and has not undergone excessive freeze-thaw cycles. Increase primary antibody concentration or extend incubation time. Ensure the secondary antibody is compatible with a mouse primary antibody host. Confirm that the target protein is expressed in your chosen cell line or tissue.
• High Background: Increase blocking time or concentration. Reduce primary antibody concentration. Increase number and duration of wash steps. Ensure all buffers are freshly prepared.
• Non-specific Bands (WB): Optimize antibody dilution. Verify sample preparation conditions. Consider using a different blocking agent (BSA vs. milk).
• Inconsistent Results: Aliquot antibody to avoid repeated freeze-thaw cycles. Standardize sample loading and preparation across experiments.
