      BV421 Mouse Anti-Human NF-κB p65 (pS529)
      BV421 Mouse Anti-Human NF-κB p65 (pS529)
      Flow cytometric analysis of NF-κB p65 (pS529) expression by TNF-treated HeLa S3 cells. Cultured cells from the human HeLa S3 (Cervical adenocarcinoma, ATCC CCL 2.2) cell line were starved overnight in Dulbecco's Minimal Eagle's Medium. The cells were harvested and washed with Dulbecco's Phosphate Buffered Saline. They were then either left untreated (dashed line histogram) or treated (37°C, 10 min) with Recombinant Human TNF protein (20 ng/mL; Cat. No. 554618; solid line histogram) and Calyculin A (50 nM; Calbiochem Cat. No. 208851). The cells were fixed (10 min; 37°C) with pre-warmed BD Cytofix™ Fixation Buffer (Cat. No. 554655), permeabilized (30 min on ice) with BD Phosflow™ Perm Buffer III (Cat. No. 558050), and washed twice with BD Pharmingen™ Stain Buffer (FBS) (Cat. No. 554656). The cells were then stained with BD Phosflow™ BV421 Mouse Anti-Human NF-κB p65 (pS529) antibody (Cat. No. 565446).  The fluorescence histograms showing NF-κB p65 (pS529) expression were derived from gated events with the forward and side light-scatter characteristics of intact HeLa S3 cells. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer 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 with BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 were removed.

      Product Notices

      1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
      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. Source of all serum proteins is from USDA inspected abattoirs located in the United States.

      K10-895.12.50

      The K10-895.12.50 monoclonal antibody recognizes the phosphorylated serine 529 (pS529) in the transactivation domain of the human NF-κB p65 subunit. Nuclear factor κB (NF-κB) is a ubiquitously expressed transcription factor that regulates the expression of many other genes. It is crucial for cellular responses to a variety of stimuli including stress and microbial pathogens that lead to immunity, inflammation, proliferation, differentiation, survival, apoptosis, and tumorigenesis. The most studied NF-κB complex consists of the p50 (also known as NF-κB1) and p65 (also known as REL-A) subunits, both containing a 300-amino acid region with homology to the Rel proto-oncogene product (RH domain). The RH domain contains motifs for dimerization, nuclear localization, and binding to specific DNA sequences. In addition to the RH domain, the p65 subunit contains the transactivation domain, which is responsible for the interaction with the inhibitor IκB and which contains phosphorylation sites. In most cell types, the p50/p65 heterodimer is located within the cytoplasm complexed to IκB. This complex prevents nuclear translocation and activity of NF-κB. In response to stimuli such as cytokines, LPS, DNA damage, and microbial infections, IκB is phosphorylated at critical residues. This phosphorylation induces dissociation of the IκB/NF-κB complex, allowing the free heterodimeric NF-κB to translocate to the nucleus. Furthermore, optimal activation of NF-κB requires phosphorylation in the transactivation domain of p65. In the nucleus, activated NF-κB dimers bind to the κB sites within promoters and enhancers and function as transcriptional regulators.

      The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.

      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.
