Product Overview
CD86 is an 80 kD immunoglobulin superfamily member also known as B7-2, B70, and Ly-58. CD86 is expressed on activated B and T cells, macrophages, dendritic cells, and astrocytes. CD86, along with CD80, is a ligand of CD28 and CD152 (CTLA-4). CD86 is expressed earlier in the immune response than CD80. CD86 has also been shown to be involved in immunoglobulin class-switching and triggering of NK cell-mediated cytotoxicity. CD86 binds to CD28 to transduce co-stimulatory signals for T cell activation, proliferation, and cytokine production. CD86 can also bind to CD152, also known as CTLA-4, to deliver an inhibitory signal to T cells.

This antibody is validated for flow cytometry applications. For intracellular targets, fix and permeabilize cells using a validated fixation/permeabilization kit (e.g., BD Cytofix/Cytoperm or similar) before staining. For surface markers, stain live or fixed cells without permeabilization. Always include a matched isotype control (Rat IgG2a, κ, Rat origin) at the same protein concentration as the test antibody to establish non-specific binding thresholds. Recommended starting dilution/concentration: FCM 2 μg/mL(0.5×106-1×106 cells).
This antibody has been experimentally validated in: Mouse. Cross-reactivity with other species has not been systematically evaluated. If your sample species is not listed, assess immunogen sequence homology to your target species ortholog. The immunogen used is: "" — higher sequence identity between species increases the probability of cross-reactivity, but experimental validation with appropriate controls is necessary before drawing scientific conclusions.
Store at 4°C valid for 12 months or -20°C valid for long term storage, avoid freeze / thaw cycles. Storage Buffer: Phosphate-buffered solution, pH 7.2, containing 0.05% non-protein stabilizer. Dialyze to completely remove the stabilizer prior to labeling.. To maintain antibody activity, avoid repeated freeze-thaw cycles. Aliquot into single-use volumes before first freeze. If working with the antibody frequently, keep a working stock at 4°C for up to 4 weeks — add 0.02% sodium azide to the working stock as a bacteriostatic agent if azide is not already present in the buffer. Monitor performance against a validated positive control when transitioning between storage aliquots or lots.
This monoclonal antibody (clone GL-1) provides highly consistent, epitope-specific recognition of CD86, making it ideal for quantitative assays, multiplex panels, and studies requiring strict reproducibility across experiments and independent laboratories. Unlike polyclonal preparations, each production batch from a single hybridoma clone generates antibody with identical epitope specificity, affinity, and isotype — ensuring reliable signal comparison in longitudinal studies or multi-site collaborations. When citing this antibody in publications, include the clone designation (clone GL-1) to enable third-party reproducibility verification.
Customization & Add-ons: Can't find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
