Description

The 17B5 monoclonal antibody specifically recognizes CD137 which is also known as 4-1BB. CD137 (4-1BB) is an ~39 kDa single-pass type I transmembrane glycoprotein that is encoded by Tnfsf9 (Tnfsf9 tumor necrosis factor ligand superfamily, member 9). Monomeric and multimeric forms of CD137 (4-1BB) are expressed on thymocytes as well as activated T cells, B cells, NK cells, monocytes, macrophages, and dendritic cells (DC). It is also expressed on T regulatory cells and may function in their proliferation. CD137 (4-1BB) plays a costimulatory role in the interactions between T cells, B cells, and antigen presenting cells as it binds to 4-1BB ligand (4-1BBL), which is also known as CD137 ligand (CD137L). The 17B5 antibody can reportedly block these costimulatory interactions.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unconjugated antibody and free dye were removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
2. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
3. An isotype control should be used at the same concentration as the antibody of interest.
4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
5. This APC-conjugated reagent can be used in any flow cytometer equipped with a dye, HeNe, or red diode laser.

N-terminalSequence Analysis	Asn-Trp-Val-Asn-Val-Ile-Ser-Asp-Leu-Lys
Purity	>95%, as determined by Coomassie stained SDS-PAGE
Formulation	0.1 µm filtered protein solution is in PBS.
Endotoxin Level	Less than or equal to 0.1 EU per μg protein as determined by the LAL method
Residual Host Cell Protein Content	≤ 0.500 ng/μg by ELISA
Concentration	500 µg/mL
Storage & Handling	Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% endotoxin-free BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week or stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
