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).

For Immunofluorescence Applications:

The use of a mounting reagent (eg, ProLong® Gold) is highly recommended to maximize the photostability of BV480.  For confocal microscopy systems, a 440 nm laser is the optimal excitation source and the recommended emission filter is a 485/20 nm bandpass filter.  

For epifluorescence microscopes with broad spectrum excitation sources, the recommended excitation and emission filters are 445/20 nm and 485/20 nm bandpass filters, respectively.  For specific multicolor imaging applications, the exact filter configurations should be optimized by the end user.

The V46-1954 monoclonal antibody specifically recognizes mouse CD304, also known as neuropilin 1 (Nrp1). It does not cross-react with neuropilin 2 (Nrp2). CD304 is a type-1 transmembrane protein that plays important roles in neuronal development, angiogenesis, and immunosuppression. Through interactions with plexins and VEGF receptors on neurons and endothelial cells, it is a co-receptor for the class III semaphorin subfamily and vascular endothelial growth factor (VEGF), respectively. The ability of the S1 protein of SARS-CoV-2 virus to bind to Nrp1, a potential mechanism for cellular infection, is being investigated. In the immune system, CD304 is expressed on natural (thymus-derived) Treg cells and may be responsible for the unsuccessful immune regulation of tumor growth.

The antibody was conjugated to BD Horizon BV480 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 436-nm and Em Max at 478-nm, BD Horizon BV480 can be excited by the violet laser and detected in the BD Horizon BV510 (525/40-nm) filter set.  BV480 has less spillover into the BV605 detector and, in general, is brighter than BV510.

The BD Horizon Brilliant Violet™ 480 (BV480) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology fluorochrome has an excitation maximum (Ex Max) of 440-nm and an emission maximum (Em Max) of 479-nm. Driven by BD innovation, BV480 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 480-nm (e.g., a 525/50 bandpass filter). The increased fluorescence intensity of BV480 and narrower emission spectra, make it a good alternative for BV510 or V500. Due to its excitation profile, BV480 will also has less cross-laser excitation with the UV laser, resulting in less spillover into UV channels compared to BV510. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
