Mouse SF20 is a secreted bone marrow stroma-derived growth factor. SF20 isnot only expressed in bone marrow and spleen stroma cells, It is expressed in resting mononuclear cells, resting CD8+ and CD19+ cells and activated CD8+ T cells. It has been shown only to bind to the surface of cells expressing the receptor TSA-1 (Thymic shared Ag-1). Reports show that SF20 stimulates the proliferation of FDCP2 (a mouse IL-3 factor-dependent hemopoietic cell line) cells and mouse lymphoid cells through TSA-1, but it does not show any myelopoietic activity. More research on SF20 and its receptor TSA-1 may help determine the role they play in the regulation of lymphocyte activation. Recombinant Mouse SF20 is a 15.8kD protein, consisting of 143 amino acid residues.
Applications
Suitable for use in ELISA and Western Blot. Other applications not tested.
Recommended Dilution
ELISA: To detect mSF-20 by direct ELISA (using 100ul/well antibody solution) a concentration of at least 0.5ug/ml of this antibody is required. This antigen affinity purified antibody, in conjunction with compatible secondary reagents, allows the detection of 0.2-0.4ng/well of recombinant mSF-20. Western Blot: To detect mSF-20 by Western Blot analysis S1012-83M can be used at a concentration of 0.1-0.2ug/ml. Used in conjunction with compatible secondary reagents the detection limit for recombinant mSF-20 is 1.5-3.0ng/lane, under either reducing or non-reducing conditions. Optimal dilutions to be determined by the researcher.
