Hox B4 (Homeobox Protein B4, HOXB4, HOX-B4, Homeobox 2F, Hox 2F, HOX 2, Hox 2.6)
Description:
Homebox transcription factors (Hox) are encoded by highly conserved developmental genes that are involved embryonic and early hematopoietic development. Specifically, Homeobox B4 (HoxB4) is a transcription factor encoded by HOXB4 gene and it is involved in the developmental regulation of specific positional identities on the anterior-posterior axis of cells. Like all members of HOX family, HoXB4 is abundantly expressed in primitive hematopoietic stem cell (HSC), but then decline with lineage-specific terminal differentiation (1). In HSC, stem cell self-renewal activity is regulated by USF1/2 binding to HoxB4, where binding possibly favors stem cell self-renewal instead of cell differentiation. Jun-B and Fra-1 has been linked as key mediators during cell proliferation and differentiation induced by HoxB4, which leads to increase expression of Cyclin D1 and G1 shortening (2).

Applications:
Suitable for use in Flow Cytometry, Western Blot, Immunoprecipitation, Immunohistochemistry and Immunocytochemistry. Other applications not tested.

Recommended Dilution:
Flow Cytometry: 1:20
Western Blot: 1:250-1:500
Immunoprecipitation: 1:40
Immunohistochemistry: 1:100-1:250

Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage, aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
