This StarBright conjugate is available for purchase as part of a multicolor flow cytometry panel. To order, add compatible products to your shopping cart, or use our Panel Selector tool to build your ideal panel. For ordering assistance or to request a sample, contact your local field representative.

This product is also available for direct purchase within a StarBright Basic Panel, which combines a minimal set of pre-selected compatible reagents.

Description

CD20 is a 33-37 kD, four transmembrane spanning protein, also known as B1 and Bp35. CD20 is expressed on pre-B-cells, resting and activated B cells (not plasma cells), some follicular dendritic cells, and at low levels on a T cell subset. CD20 is heavily phosphorylated on activated B cells and malignant B cells. Homo-oligomeric complexes of CD20 are thought to form Ca²⁺ conductive ion channels in the plasma membrane of B cells. The CD20 molecule is involved in B-cell activation and is associated with various Src family kinases (Lyn, Lck, Fyn). It exists in a complex with MHC class I and II, CD53, CD81, and CD82.

Technical data sheet

Product Details

Verified Reactivity: Human, Cynomolgus, Rhesus
Antibody Type: Monoclonal
Host Species: Mouse
Immunogen: Human tonsillar B cells
Formulation: Phosphate-buffered saline, containing 0.09% sodium azide, 0.05% Tween 20, 0.1% PEG 3350, 0.1% Pluronic F68, and 1% BSA (origin USA)
Preparation: The antibody was purified by affinity chromatography and conjugated with StarBright UltraViolet 665 under optimal conditions.
Concentration: Lot-specific (to obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.) The concentration relates to the dye component of the conjugate.
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
Application: FC - Quality tested
Recommended Usage: Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µL per million cells in 100 µL staining volume or 5 µL per 100 µL of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

* StarBright UltraViolet 665 has a maximum excitation of 340 nm and a maximum emission of 669 nm.

StarBright dyes are powered by Bio-Rad®. STARBRIGHT is a trademark of Bio-Rad Laboratories, Inc.
Excitation Laser: Ultraviolet Laser (355 nm)
Application Notes: The epitope recognized by clone 2H7 has been mapped to the sequence YNCEPANPSEKNSPST which lies in the large extracellular loop of human CD20. Additional reported applications (for the relevant formats) include: immunoprecipitation⁴ and immunohistochemical staining of acetone-fixed frozen sections⁵.

Related FAQs

What is the difference between two anti human CD20 clones 2H7 and 1412?: For clone 1412: This clone specifically recognizes cytoplasmic domain of CD20 and thus can only be used for intracellular flow cytometry. In this instance you will need to include the fixation and permeabilization steps. Please follow the intracellular flow cytometry staining protocol.

For clone 2H7: This clone is ok for regular surface staining for CD20 and there is no need for any fixation and permeabilization steps.

Our technical protocols can be found here.
What is a “StarBright panel”?: A StarBright panel is a multiplex panel that includes at least one StarBright conjugate.
Will my StarBright panel be provided as a cocktail?: StarBright products purchased as part of a panel or StarBright Basic Panel will be provided in individual vials. To order premade cocktails, please contact our Custom Solutions Team.
Are StarBright GMP/ASR products available?: StarBright ASR and GMP products are coming soon.
Are StarBright custom products available?: Yes, please contact our Custom Solutions Team.
Will StarBright isotype controls be offered?: We are not planning to offer StarBright isotype controls at this time. Fluorescence Minus One (FMO) controls should be used to define gating boundaries.
What amount of a StarBright conjugate should I use?: Antibody conjugates should be titrated for optimal performance in each application. To directly compare performance with a traditional or polymer-conjugated antibody, we recommend using the same volume of each product for analysis. Due to differences in the quantification of product mass, StarBright Dyes are prepared in equivalent volumes.
Why shouldn’t I compare the mass (μg) of a StarBright conjugate to a traditional or polymer conjugate?: For StarBright conjugates, the reported mass refers to the mass of the dye component. For traditional conjugates, the reported mass refers to the mass of the antibody component. This is because traditional conjugates have multiple dye molecules attached to one antibody, while StarBright conjugates have multiple antibodies attached to a single StarBright Dye.
