Alexa Fluor™ 488 Mouse Anti-Human IDO1
Alexa Fluor™ 488 Mouse Anti-Human IDO1
Multicolor flow cytometric analysis of IDO1 expression on human peripheral blood mononuclear cells (PBMCs). PBMCs were cultured in complete tissue culture medium without (Left Plot) or with (Right Plot) lipopolysaccharide (LPS) (1 ug/ml, 20-24h, 37°C). The cells were harvested, then fixed and permeabilized using BD Cytofix/Cytoperm™ solution (Cat. No. 554722) and BD Perm/Wash™ buffer (Cat. No. 554723). The cells were then stained with BD Horizon™ BV421 Mouse Anti-Human CD11b (Cat. No. 562632) and Alexa Fluor™ 488 Mouse Anti-Human IDO1 antibody (Cat. No. 567853/567854). Bivariate pseudocolor density plots showing the correlated expression of IDO1 (or Ig Isotype control staining) versus CD11b were derived from gated events with the forward and side light-scatter characteristics of intact PBMCs. Flow cytometric analysis was performed using a BD LSRFortessa™ X-20 Flow Cytometer System.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. 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 unreacted dye was removed.

Recommended Assay Procedures

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 cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

Product Notices

  1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. Alexa Fluor® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).
  3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  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 reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  7. An isotype control should be used at the same concentration as the antibody of interest.

V50-1886

The V50-1886 monoclonal antibody specifically binds to human IDO1, or indoleamine 2, 3-dioxygenase 1, a rate-limiting enzyme in the catabolism of tryptophan.  IDO1 is expressed in normal epithelial, endothelial and myeloid cells and in tumor cells. Its expression is induced by interferon gamma and increases in viral and bacterial infections. The reduction of tryptophan and increase in its metabolites that are mediated by IDO1 have critical immunosuppressive and bactericidal effects.

Alexa Fluor™ 488
Alexa Fluor™ 488 Dye is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 517-nm. Alexa Fluor™ 488 is designed to be excited by the Blue laser (488 nm) and detected using an optical filter centered near 520-nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
