Description
The mAb3 monoclonal antibody specifically recognizes Neuropilin-1 (NRP1), also known as CD304, Blood dendritic cell antigen 4 (BDCA4), and Vascular endothelial cell growth factor 165 receptor (VEGF165R). Neuropilin-1 (CD304) is an ~140 kDa type I transmembrane glycoprotein that is encoded by NRP1 and expressed on plasmacytoid dendritic cells (DC), thymocytes, regulatory T cells, a subset of T follicular helper cells, endothelial cells, neurons, and certain tumor cells. This multifunctional receptor can mediate the interaction, growth, survival, and migration of a variety of normal and tumor cells including prostate and breast cancer cells. Neuropilin-1 (CD304) may play a role in the interactions between some T cells and dendritic cells. It is involved in the development of the nervous and cardiovascular systems. CD304 complexes with Plexin-A family members to bind chemorepellent Class 3 Semaphorins and guide neuronal axon growth. It also functions as a coreceptor with VEGFR2/CD309 to stimulate angiogenesis in response to VEGF165. It also functions as a co-receptor that can facilitate the entry of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) into host cells.
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.
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.
1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
2. Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
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. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
5. An isotype control should be used at the same concentration as the antibody of interest.
6. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
7. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

8. Researchers should determine the optimal concentration of this reagent for their individual applications.
9. 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.
