BD Phosflow™ PerCP-Cy™5.5 Mouse Anti-Human CD20
Clone H1 (also known as FB1) (RUO)
Analysis of CD20 (cytoplasmic) in human peripheral blood lymphocytes. Human peripheral blood mononuclear cells were fixed with pre-warmed BD Cytofix™ buffer (Cat. No. 554655) for 10 minutes at 37ºC and permeabilized with BD Phosflow™ Perm Buffer II (Cat. No. 558052) on ice for 30 minutes. The cells were then stained with either PerCP-Cy5.5 Mouse IgG2a, κ, isotype control (Cat. No. 558020, dashed line) or PerCP-Cy5.5 Mouse Anti-Human CD20 (cytoplasmic) (solid line). For data analysis, lymphocytes were selected by their scatter profile. CD20 (cytoplasmic) was not detected in the monocytes (not shown). Flow cytometry was performed on a BD FACSCalibur™ flow cytometry system.

준비 및 보관
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 PerCP-Cy5.5 under optimum conditions, and unconjugated antibody and free PerCP-Cy5.5 were removed. Storage of PerCP-Cy5.5 conjugates in unoptimized diluent is not recommended and may result in loss of signal intensity.
권장 분석 절차
This antibody conjugate is suitable for intracellular staining of human whole blood (using BD Phosflow™ Lyse/Fix Buffer) and peripheral blood mononuclear cells (using BD Cytofix™ Fixation Buffer or BD Phosflow™ Fix Buffer I). Any of the three BD Phosflow™ permeabilization buffers may be used.
제품 고시
- 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).
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- 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.
- PerCP-Cy5.5–labelled antibodies can be used with FITC- and R-PE–labelled reagents in single-laser flow cytometers with no significant spectral overlap of PerCP-Cy5.5, FITC, and R-PE fluorescence.
- PerCP-Cy5.5 is optimized for use with a single argon ion laser emitting 488-nm light. Because of the broad absorption spectrum of the tandem fluorochrome, extra care must be taken when using dual-laser cytometers, which may directly excite both PerCP and Cy5.5™. We recommend the use of cross-beam compensation during data acquisition or software compensation during data analysis.
- 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.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- An isotype control should be used at the same concentration as the antibody of interest.

항체 세부 정보
H1
The H1 (FB1) antibody specificially binds to a cytoplasmic domain of CD20. CD20 is a 33-37-kDa four transmembrane phosphoprotein that is expressed by B lymphocytes from the pre-B stage and most malignant B cells and is lost during plasma cell differentiation. Low level CD20 expression is observed on a subset of normal circulating T lymphocytes, and CD20-positive T-cell lymphomas have been reported. The CD20 molecule is associated with membrane lipid raft domains, acts as a channel for calcium ions, and is involved in the regulation of B cell activation and survival. The cytoplasmic domain regions are serine and threonine rich and contain multiple phosphorylation consensus sequences.

PerCP-Cy5.5
PerCP-Cy5.5 dye is part of the BD blue family of dyes. This tandem fluorochrome is comprised of a fluorescent protein complex (PerCP) with an excitation maximum (Ex Max) of 482 nm and an acceptor dye with an emission maximum (Em Max) at 676 nm. PerCP-Cy5 is designed to be excited by the blue laser (488-nm) and detected using an optical filter centered near 680 nm (e.g., a 695/40 nm bandpass filter). The donor dye can be partially excited by the Violet (405-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
