Isotype

Mouse IgG2b

Specificity

The mouse monoclonal antibody 162 recognizes an extracellular epitope of human CD319, a transmembrane glycoprotein expressed by cytotoxic T cells, activated B cells, NK cells, and mature dendritic cells.

Application

FC (QC tested)

Application details

Flow cytometry: The reagent is designed for analysis of human blood cells using 10 μl reagent / 100 μl of whole blood or 10⁶ cells in a suspension. The content of a vial (1 ml) is sufficient for 100 tests.

Reactivity

Human

Immunogen

Recombinant extracellular domain of human CD319 (204 aa) fused with Fc part of human IgG1

Preparation

Purified antibody is conjugated with R-phycoerythrin (PE) under optimum conditions. Unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.

Formulation

Stabilizing phosphate buffered saline (PBS), pH 7.4, 15 mM sodium azide

Storage and handling

Store at 2-8°C. Protect from prolonged exposure to light. Do not freeze.

Antigen description

CD319 is a homophilic type I transmembrane protein with two intracellular immunoreceptor tyrosine-based switch motives (ITSMs). It is expressed by cytotoxic T cells, activated B cells and plasma cells, NK cells, and mature dendritic cells. CD319 triggers NK cell-mediated cytotoxicity. Ligation of CD319 can induce proliferation, cell adhesion, cytokine secretion, and cytotoxicity of T cells and NK cells.

Anti-human CD319 PE antibody (clone 162) works in flow cytometry application.

Analysis of the antibody staining profile was performed on blood leukocytes isolated from buffy coats. HCDM CDMaps standardized procedures (Kuzilkova D et al. Front Immunol. 2022;13:827898) were used for cell isolation and surface staining of blood leukocytes, with the modification of staining protocol using cytometry test tubes.
Mouse monoclonal anti-human CD319 PE antibody (clone 162) was used in amount of 10 µl in 100 µl of blood sample (2 x 10⁶ cells).

Expression profiling on peripheral blood subsets using Anti-human CD319 PE antibody (clone 162).

HCDM CDMaps standardized procedures (Kuzilkova D et al. Front Immunol. 2022;13:827898) were used for cell isolation and surface staining of blood leukocytes, with the modification of staining protocol using cytometry test tubes.
Suspension of blood leukocytes isolated from buffy coats (2 x 10⁶ cells) was added to the mixture of anti-human CD319 PE antibody (clone 162, 10 μl reagent / 100 μl of stained blood sample) and Monocyte Blocking Buffer (#ED7747), vortexed and incubated for 20 min. Next, optimized backbone antibody panels (HLDA Innate and HLDA Adaptive) were added to test tubes, vortexed and incubated for 20 min. The residual erythrocytes were lysed with 2 ml of 10× diluted EXCELLYSE Easy solution (#ED7066) and incubated for 10 min. Finally, samples were centrifuged (670 g, 5 min.), supernatant removed and the cell pellet was resuspended in 200 µl of PBS for acquisition.
