BV421 Mouse Anti-Human Cytokeratin
BV421 Mouse Anti-Human Cytokeratin
Flow cytometric analysis of cytokeratin expression in human SK-BR-3 cells. Cells from the human SK-BR-3 (Breast adenocarcinoma, ATCC HTB-30) cell line were incubated with 1X BD FACS™ Lysing Solution (Cat. No. 349202), permeabilized with BD FACS™ Permeabilizing Solution 2 (Cat. No. 340973/347692), and washed with BD Pharmingen™ Stain Buffer (FBS) (Cat. No. 554656). The cells were then stained with either BD Horizon™ BV421 Mouse IgG2a, κ Isotype Control (Cat. No. 562439; dashed line histogram) or BD Horizon BV421 Mouse Anti-Human Cytokeratin antibody (Cat. No. 564709; solid line histogram). The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of intact 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.

CAM5.2

The CAM5.2 monoclonal antibody specifically recognizes cytokeratin having a primary reactivity with human keratin proteins that correspond to Moll's peptides #7 (48 kDa) and #8 (52 kDa). Cytokeratin 7 and 8 are type II cytoskeletal keratins. These cytoskeletal proteins provide structural integrity for epithelial cells and may serve other functions as well. They are expressed in epithelia cells that comprise normal human tissues. Although these cytokeratins are not normally expressed in stratified squamous epithelium, they may be expressed in some squamous cell carcinomas. The CAM 5.2 antibody stains most epithelial-derived tissue, including liver, renal tubular epithelium, and hepatocellular and renal cell carcinomas.

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.
