Description

The ACK2 monoclonal antibody reacts with mouse CD117, also known as c-Kit receptor, Steel factor receptor and stem cell factor receptor. A member of the tyrosine kinase receptor family, this 145 kDa molecule is expressed by a majority of hematopoietic progenitor cells characterized in the mouse bone marrow as a small subset of cells positive for Sca-1 and Thy1 (Thy1^lo) and negative for lineage markers. The interaction of the mouse c-kit receptor and steel factor promotes the proliferation and differentiation of hematopoietic progenitor cells. CD117 is also expressed by mast cells and plays a role in signaling and activation of these cells. ACK2 has been reported to be a blocking antibody.

Applications Reported

For research use only, not for diagnostic or therapeutic use. This ACK2 antibody has been reported for use in flow cytometric analysis.

The photo-emission properties and compensation required for Alexa Fluor® 750 are similar to APC-Cy7; however Alexa Fluor® 750 has several advantages when compared to APC-Cy7. The Alexa Fluor® 750 has peak emission of 779 nm, and usually has a slightly higher mean fluorescent intensity when compared to the same clone conjugated with APC-Cy7, which has peak emission of 767 nm. Furthermore, Alexa Fluor® 750 is considered to be a more photostable fluorochrome as compared with APC-Cy7. It is advised not to use fixatives with Alexa Fluor® 750 as this may lead to degradation of the fluorochrome and loss of staining.

Applications Tested

This ACK2 antibody has been tested by flow cytometric analysis of mouse bone marrow cell suspensions. This can be used at less than or equal to 0.5 μg per million cells in a 100 μl total staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
