Human peripheral blood lymphocytes were surface stained with CD19 Brilliant Violet 421™ and then were treated with True-Nuclear™ Transcription Factor Buffer Set. Cells were then stained with anti-human SPI1 (clone 7C6B05) Alexa Fluor® 647 (top) or mouse IgG1, κ Alexa Fluor® 647 isotype control (bottom).

    Human peripheral blood monocyte-derived macrophages were fixed with 1% paraformaldehyde (PFA) and permeabilized with 0.5% TX-100. Then the cells were stained with 5 µg/ml of SPI1 (clone 7C6B05) Alexa Fluor® 647 (red) overnight at 4°C and followed by 5 µg/ml of CD11b Alexa Fluor® 488 (green) staining for 30 minutes. Nuclei were counterstained with DAPI (blue). The image was captured with 60X objective.

Description

SPI1 is a transcription factor belonging to the E26-transformation-specific (Ets) family and is exclusively expressed in hematopoietic cells. SPI1 regulates cell fate decisions during differentiation of hematopoietic stem cells, which is crucial for the development of lymphoid and myeloid cell lineages. SPI1-deficient mice lack macrophages, neutrophils, and B lymphocytes, and they die before or shortly after birth. Abnormally regulated expression of SPI1 can lead to developmental defects as well as occurring malignancy. Overexpression of SPI1 blocks erythroid differentiation and inhibits cell death.  Mice carrying a mutant SPI1 allele show decreased SPI1 expression and develop acute myeloid leukaemia (AML), suggesting the role of SPI1 in oncogenesis.

Recommended Usage

Each lot of this antibody is quality control tested by intracellular flow cytometry using our True-Nuclear™ Transcription Factor Staining Protocol. For flow cytometric staining using µsize, the suggested use of this reagent is 0.5 µg per million cells in 100 µl volume. For flow cytometric staining using tests sizes, 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. For immunocytochemistry, a concentration range of 2.5 - 5.0 µg/ml is recommended. It is recommended that the reagent be titrated for optimal performance for each application.

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