Our Abpromise guarantee covers the use of ab89896 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use at an assay dependent concentration.
IHC-Fr 1/20 - 1/200.
Neutralising Use at an assay dependent concentration. Proliferation of human PBMCs elicited by TNFSF4 (25ng/mL) can be neutralized by increasing concentrations of ab89896 in a dose-dependent manner. The ED50 is between 40-80ng/mL.
Flow Cyt 1/50 - 1/100.

ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.



  • Function
    Cytokine that binds to TNFRSF4. Co-stimulates T-cell proliferation and cytokine production.
  • Involvement in disease
    Genetic variations in TNFSF4 influence susceptibility to systemic lupus erythematosus (SLE) [MIM:152700]. SLE is a chronic, inflammatory and often febrile multisystemic disorder of connective tissue. It affects principally the skin, joints, kidneys and serosal membranes. It is thought to represent a failure of the regulatory mechanisms of the autoimmune system. Note=The upstream region of TNFSF4 contains a single risk haplotype for SLE, which is correlated with increased expression of both cell-surface TNFSF4 and TNFSF4 transcripts. Increased levels of TNFSF4 are thought to augment T cell-APC interaction and the functional consequences of T cell activation, thereby destabilizing peripheral tolerance.

  • ab89896 staining CD252 in Cynomolgus Monkey lymph node tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 10% serum for 20 minutes at room temperature; antigen retrieval was enzymatic. Samples were incubated with primary antibody (1/25) for 30 minutes at room temperture. An undiluted Biotin-conjugated Donkey anti-mouse IgG polyclonal was used as the secondary antibody.

For each lot of ab89896, the level of LPS is <0.01EU/ug IgG.

Thank you for your email.

Here are some answers:

1. Did Abcam use fresh or thawed PBMC?

We used freshed ones!

2. How many PBMC were culture in each well?, what media did Abcam use? Did they

Thank you for your interest in ab89896. I have confirmed with the laboratory that the endotoxin level is <0.5EU/mg antibody. I hope this information is helpful. Please do not hesitate to contact me if you have any additional questions.

Human recombinant TNFSF4 (with Poly-His taq) can stimulate the proliferation of human PBMCs, in the presence of cross-linking antibody and PHA (phytohemagglutinin). Under this condition, proliferation of human PBMCs elicited by TNFSF4 (25ng/mL) can...
