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 that minimize unconjugated dye and antibody.

Recommended Assay Procedures

BD™ CompBeads can be used as surrogates to assess fluorescence spillover (Compensation).  When fluorochrome conjugated antibodies are bound to 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 CompBead to ensure that BD Comp beads are appropriate for your specific cellular application.

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes 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. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).

Product Notices

  1. 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.
  2. Researchers should determine the optimal concentration of this reagent for their individual applications.
  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.

Avas 12α1

The Avas 12α1 monoclonal antibody specifically binds to fetal liver kinase 1 (Flk-1) which is also known as CD309. Flk-1 is a receptor protein tyrosine kinase which is closely related to CD117 (c-kit) and CD140a (PDGF Receptor α chain) of the immunoglobulin superfamily. Flk-1, also known as VEGF Receptor-2 (VEGF-R2 or VEGFR2), is a receptor for vascular endothelial growth factor (VEGF). It is expressed, at the mRNA and protein levels, on distinct sets of mesoderm during gastrulation and on endothelial cells in embryonic and adult tissues. In vivo and in vitro studies indicate that Flk-1 is required for the embryonic development of vascular endothelial and hematopoietic cells.

The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max near 407 nm and Em Max near 421 nm, BD Horizon BV421 can be excited by the violet laser (405 nm) and detected with a 450/50 nm filter. BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue™ conjugates. Due to nearly identical excitation and emission properties but different spillover characteristics, BD Horizon BV421, Pacific Blue™, and BD Horizon V450 cannot be used simultaneously.

BV421
The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
