CD19 is a 95 kD type I transmembrane glycoprotein also known as B4. It is a member of the immunoglobulin superfamily expressed on B-cells (from pro-B to blastoid B cells, absent on plasma cells) and follicular dendritic cells. CD19 is involved in B cell development, activation, and differentiation. CD19 forms a complex with CD21 (CR2) and CD81 (TAPA-1), and functions as a BCR co-receptor.

- Reactivity
- Human
- Antibody Type
- Monoclonal
- Host Species
- Mouse
- Formulation
- Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and BSA (origin USA)
- Preparation
- The antibody was purified by affinity chromatography, and conjugated with PE/Cyanine5 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.)
- 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.
- Excitation Laser
-
Blue Laser (488 nm)
Green Laser (532 nm)/Yellow-Green Laser (561 nm)
- Application Notes
-
Additional reported applications (for the relevant formats) include: immunohistochemical staining of acetone-fixed frozen tissue sections8 and blocking of B cell proliferation. Clone HIB19 is not recommended for formalin-fixed paraffin-embedded sections. The Ultra-LEAF™ purified antibody (Endotoxin < 0.01 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (Cat. No. 302267 & 302268).
Clone HIB19 partially blocks anti-human CD19 clones 4G7 and SJ25C1 staining based on in-house testing
- Additional Product Notes
-
BioLegend is in the process of converting the name PE/Cy5 to PE/Cyanine5. The dye molecule remains the same, so you should expect the same quality and performance from our PE/Cyanine5 products. Please contact Technical Service if you have any questions.
