FC - Quality tested

Application Notes:

Additional reported applications (for the relevant formats) include: immunofluorescence3 and immunohistochemical staining of acetone-fixed frozen sections4.

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 ≤ 0.25 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for other applications.

* Alexa Fluor® 647 has a maximum emission of 668 nm when it is excited at 633nm / 635nm.

C57BL/6 splenocytes stained with M5/114

C57BL/6 splenocytes stained with M5/114 (I-A/I-E) PE and 33D1 Alexa Fluor® 647


33D1 antigen, also known as DCIR2 (dendritic cell inhibitory receptor 2), is reported to be a dendritic cell marker on subpopulation DC in the spleen, thymus, and Peyer's patch. It is reported that most N418 (CD11c)+ cells in spleen are also 33D1 positive. Bone marrow dendritic cells upregulate 33D1 antigen expression after incubation with GM-CSF.

Other Names: Dendritic Cell Marker, 33D1, DCIR2 (dendritic cell inhibitory receptor 2)
Structure: The antigen recognized by 33D1 is yet unknown.
Distribution: 33D1 antigen was reported on dendritic cell populations from mouse thymus, spleen lymph nodes and Peyer patches. Bone marrow dendritic cells can be induced to express 33D1 antigen in the presence of GM-CSF. In mouse spleen, most N418+ cells are also 33D1 positive.
Function: GM-CSF is reported to increase expression of 33D1 antigen on dendritic cells from bone marrow cells and IL-4 reported to down regulate the 33D1 antigen.
