Aqueous buffered solution containing ≤0.09% sodium azide.


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 with BD Horizon BUV661 under optimal conditions that minimize unconjugated dye and antibody.


For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) are used in the same experiment.  Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.  The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions.  More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794).


  1. This antibody was developed for use in flow cytometry.
  2. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
  3. Researchers should determine the optimal concentration of this reagent for their individual applications.
  4. An isotype control should be used at the same concentration as the antibody of interest.
  5. 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.

The TX45 monoclonal antibody recognizes human CD300c which is also known as Leukocyte immunoglobulin-like receptor (LIR), CMRF35-like molecule 6 (CLM-6), or Immunoglobulin superfamily member 16 (IGSF16). CD300c is a type I transmembrane glycoprotein that belongs to the CMRF family within the Ig superfamily. CD300c is primarily expressed on myeloid cells and has also been detected on some T cells, B cells, and NK cells. Amongst freshly-isolated leucocytes, the TX45 antibody only detects CD300c expressed on monocytes.  CD300c is involved in the regulation of proinflammatory cytokine production by leucocytes.

The antibody was conjugated to BD Horizon™ BUV661 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome of BD Horizon BUV395 with an Ex Max of 348-nm and an acceptor dye with an Em Max at 661-nm. BD Horizon Brilliant BUV661 can be excited by the ultraviolet laser (355 nm) and detected with a 670/25 filter and a 630 nm LP.  Due to cross laser excitation of this dye, there may be significant spillover into channels detecting APC-like emissions (eg, 670/25-nm filter).


Due to spectral differences between labeled cells and beads, using BD™ CompBeads can result in incorrect spillover values when used with BD Horizon BUV661 reagents. Therefore, the use of BD CompBeads or BD CompBeads Plus to determine spillover values for these reagents is not recommended. Different BUV661 reagents (eg, CD4 vs. CD45) can have slightly different fluorescence spillover therefore, it may also be necessary to use clone-specific compensation controls when using these reagents.

The BD Horizon Brilliant™ Ultraviolet 661 (BUV661) Dye is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This tandem fluorochrome is comprised of a BUV395 donor with an excitation maximum (Ex Max) of 350-nm and an acceptor dye with an emission maximum (Em Max) at 660-nm. BUV661, driven by BD innovation, is designed to be excited by the ultraviolet laser (355-nm) and detected using an optical filter centered near 660-nm (e.g., 670/25 bandpass filter). The acceptor dye can be excited by the Red (628–640-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
