What Is TNFSF14 and Why Is It Studied?

TNFSF14, commonly referred to as LIGHT (Homologous to Lymphotoxins, Inducible expression, competes with HSV Glycoprotein D for Herpesvirus Entry Mediator, a receptor expressed by T lymphocytes), is a type II transmembrane protein and a member of the tumor necrosis factor (TNF) superfamily. It is expressed primarily on activated T cells, natural killer (NK) cells, monocytes, and granulocytes.

TNFSF14 binds to two main receptors: Herpesvirus Entry Mediator (HVEM/TNFRSF14) and Lymphotoxin Beta Receptor (LTβR). Through these interactions, TNFSF14 plays critical roles in T cell co-stimulation, dendritic cell maturation, antitumor immunity, and the regulation of inflammatory responses. Its involvement in autoimmune diseases, cancer immunology, and viral pathogenesis makes it a significant target for both basic and translational research.

Key Applications of TNFSF14 Mouse mAb (Ab349347)

The TNFSF14 Mouse mAb (Ab349347) is designed for use in a range of standard immunological research applications. Typical applications for anti-TNFSF14 monoclonal antibodies of this class include:

• Western Blotting (WB): Detection of TNFSF14 protein in cell lysates or tissue homogenates under denaturing conditions.
• Enzyme-Linked Immunosorbent Assay (ELISA): Quantitative or qualitative detection of TNFSF14 in biological samples.
• Immunofluorescence (IF): Visualization of TNFSF14 expression and localization in fixed cells or tissue sections.
• Flow Cytometry (FC): Analysis of TNFSF14 surface expression on immune cell populations.
• Immunoprecipitation (IP): Isolation of TNFSF14 protein complexes for downstream analysis.

Storage, Handling, and Reconstitution Guidelines

Proper storage and handling of TNFSF14 Mouse mAb (Ab349347) is essential to maintain antibody activity and ensure reproducible experimental results. General best-practice guidelines for monoclonal antibodies of this type include:

• Storage Temperature: Store at –20 °C for long-term storage. Avoid repeated freeze–thaw cycles, which can denature the antibody and reduce activity.
• Working Aliquots: Upon receipt, consider preparing single-use aliquots to minimize freeze–thaw cycles.
• Reconstitution: If supplied as a lyophilized powder, reconstitute with the volume of sterile distilled water or PBS specified on the datasheet. Allow the vial to equilibrate to room temperature before opening, and mix gently; do not vortex.
• Carrier Protein: For dilute antibody solutions, adding a carrier protein such as 0.1–1% BSA in PBS can help prevent adsorptive losses.
• Expiry: Refer to the lot-specific Certificate of Analysis (CoA) for the expiry date.

Always refer to the product datasheet for Ab349347 for lot-specific storage instructions.

Troubleshooting Common Issues with TNFSF14 Mouse mAb

Researchers may occasionally encounter technical challenges when using TNFSF14 Mouse mAb. The following guidance addresses the most frequently reported issues:

• No Signal / Weak Signal: Verify that the antibody concentration and incubation time are optimized for your application. Ensure the secondary antibody is anti-mouse and is compatible with your detection system. Check that the antigen is present in your model system using a positive control lysate.
• High Background: Increase blocking stringency (e.g., use 5% non-fat milk or BSA). Optimize antibody dilution and washing steps. Ensure primary and secondary antibody incubation conditions are appropriate.
• Non-Specific Bands (WB): Consider using a more stringent washing buffer or reducing antibody concentration. Verify sample preparation protocols to minimize protein degradation.
• Inconsistent Results Between Lots: Always request a Certificate of Analysis for each new lot. If switching lots, re-optimize critical parameters such as dilution and incubation conditions.
