PE Mouse Anti-MR1
PE Mouse Anti-MR1
Flow cytometric analysis of MR1 expression on Human peripheral blood lymphocytes. Human peripheral blood mononuclear cells (PBMCs) were either cultured (16 h) with Acetyl-6-Formylpterin (+ Ac-6-FP; 2.3 µg/ml (10 µM); Cayman Chemicals Cat. No. 23303) or without Ac-6-FP (No Ac-6-FP) as indicated. The cells were then preincubated with Human BD Fc Block™ (Cat. No. 564219/564220) and stained with either PE Mouse IgG2a, κ Isotype Control (Cat. No. 553457; dotted line histograms) or PE Mouse Anti-MR1 antibody (Cat. No. 568011; solid line histograms) at 0.5 µg/test. DAPI Solution (Cat. No. 564907) was added to cells right before analysis. The fluorescence histograms showing MR1 expression (or Ig Isotype control staining) were derived from gated events with the forward and side light-scatter characteristics of viable (DAPI-negative) lymphocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

准备和存储

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 unconjugated antibody and free dye were removed.

推荐的实验流程

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.

  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. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  6. Species cross-reactivity detected in product development may not have been confirmed on every format and/or application.
  7. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).

26.5

The 26.5 monoclonal antibody specifically recognizes MHC-related protein 1 (MR1). MRI is a nonclassical MHC class Ib molecule. It is comprised of a ~40 kDa, highly conserved transmembrane a heavy chain that is a type I glycoprotein which is noncovalently-associated with an invariant ß2-microglobulin (ß2m) light chain. The N-terminal extracellular region of the HLA class I heavy chain is comprised of three domains (a1, a2, and a3). The a1 and a2 domains form a closed antigen-binding groove that accommodates small antigens whereas the a3 domain interacts with ß2m. MR1 is an antigen-presenting molecule that is specialized in displaying metabolites derived from microbial riboflavin biosynthesis to a small population of aß T-cells expressing an invariant TCR a chain called mucosal-associated invariant T-cells (MAIT). This function is essential to the development and expansion of MAIT cells. The 8F2.F9 and 26.5 monoclonal antibodies reportedly bind to different MRI epitopes. Clone 26.5 has been shown to crossreact with mouse and rat as well as human MR1.

PE
R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
