Alexa Fluor® 647 Mouse Anti-Human CD288 (TLR8)
Alexa Fluor® 647 Mouse Anti-Human CD288 (TLR8)
Multiparameter flow cytometric analysis of human CD288 (TLR8) expression in human peripheral blood leucocyte populations. Human peripheral blood cells were treated with BD Phosflow™ Lyse/Fix Buffer (Cat. No. 558049) to lyse erythrocytes and fix leucocytes. The leucocytes were permeabilized using BD Perm/Wash™ Buffer (Cat. No. 554723) and stained with either Alexa Fluor® 647 Mouse IgG1, κ Isotype Control (Cat. No. 557732; Left Plot) or Alexa Fluor® 647 Mouse Anti-Human CD288 (TLR8) antibody (Cat. No. 566327; Right Plot) at 0.06 µg/test. Data shown on this Technical Data Sheet are not lot specific. Two-parameter flow cytometric contour plots showing the correlated expression of CD288 (TLR8) [or Ig Isotype control staining] versus side light-scatter (SSC-A) signals were derived from gated events with the forward and side light-scatter characteristics of intact leucocyte populations. Flow cytometric analysis was performed using a BD LSRFortessa™ Cell Analyzer 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 Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. 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.
  4. The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
  5. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).

44C143

The 44C143 monoclonal antibody specifically binds to CD288 which is also known as the Toll-like receptor 8 (TLR8). CD288 is a type 1 transmembrane glycoprotein that belongs to the Toll-like receptor (TLR) family whose members play fundamental roles in pathogen recognition and activation of inflammatory and immune responses. CD288 is expressed in the endosomal and lysosomal compartments of neutrophils, monocytes, macrophages and dendritic cells. CD288 binds single-stranded microbial RNA and is involved in triggering leucocyte responses against bacteria, and single-stranded or double-stranded RNA viruses. Ligand-bound CD288 triggers the MyD88/NF-κB signal pathway leading to antimicrobial cellular responses including the release of proinflammatory cytokines such as TNF, IL-12, and MIP-1α/CCL3.

Alexa Fluor™ 647
Alexa Fluor™ 647 Dye is part of the BD red family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 653-nm and an emission maximum (Em Max) at 669-nm. Alexa Fluor 647 is designed to be excited by the Red laser (627-640 nm) and detected using an optical filter centered near 520-nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
