Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.
This product is a recombinant monoclonal antibody, which offers several advantages including:
- - High batch-to-batch consistency and reproducibility
- - Improved sensitivity and specificity
- - Long-term security of supply
- - Animal-free batch production
For more information, read more on recombinant antibodies.
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.
This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
The recommended antibody orientation is based on internal optimization for ELISA-based assays. Antibody orientation is assay dependent and needs to be optimized for each assay type. Please note that the range provided for this antibody is only an estimation based on the performance of the product using the recommended antibody pair. Performance of the antibody pair will depend on the specific characteristics of your assay. We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibody in your assay.

- Activity summary
CD137 also known as 4-1BB or TNFRSF9 is a protein that functions as a costimulatory receptor in the immune system. It belongs to the tumor necrosis factor receptor (TNFR) superfamily. CD137 has a mass of approximately 30 kDa. Expression of CD137 occurs mainly on activated T lymphocytes including both CD8+ and CD4+ T cells as well as natural killer (NK) cells dendritic cells and monocytes. The CD137 ligand (CD137L) is the counterpart that engages this receptor transmitting signals important for immune response regulation.
- Biological function summary
CD137 plays an important role in T cell activation and survival. It is a member of a receptor-ligand system that enhances immune cell functions. CD137 is part of a receptor complex that when bound by its ligand CD137L promotes cell proliferation and cytokine production. It also supports the development of memory T cells contributing to the body's ability to mount long-term immune responses.
- Pathways
CD137 takes part in the NF-kB signaling and MAPK pathways. These pathways are vital for regulating immune responses and inflammation. CD137 signaling through these pathways involves interaction with proteins such as TRAF1 and TRAF2 which help mediate downstream effects critical for cell survival and proliferation. These interactions enhance the body's defense against pathogens and tumors.
- Associated diseases and disorders
CD137 is associated with cancer immunotherapy and autoimmune diseases. In cancer CD137 enhances the anti-tumor activity of immune cells making it a target for immunotherapy strategies. For autoimmune diseases abnormal CD137 expression can lead to excessive immune responses contributing to disease pathogenesis. The protein is also connected to TNF-alpha through its involvement in inflammation suggesting potential intervention points for modulating immune response in related diseases.
