Clone Host Grade Applications Monoclonal Rat Affinity Purified E B FC

4-1BB Ligand is a type II transmembrane glycoprotein belonging to the TNF superfamily (TNFSF9). It is expressed on activated antigen presenting cells (APCs) and on most T and B lymphoma cell lines. Soluble 4-1BB Ligand can be released from the cell surface following cellular activation via proteolytic cleavage. 4-1BB Ligand exists as a noncovalent homotrimer and interacts with 4-1BB (TNFRSF9) to provide T cell costimulatory signals and dendritic cell activation.
Catalog #	0004-01D
Applications	Suitable for use in Western Blot, Flow Cytometry and ELISA. Other applications not tested.
Recommended Dilution	Western Blot: 1-2ug/ml. The detection limit is ~1ng/lane under non-reducing and reducing conditions.
	Flow Cytometry: 25ug/ml. 10ul of the diluted solution labels 1-2.5 x 10e5 cells in a total reaction volume 200ul. The binding of unlabeled monoclonal antibodies may be visualized by adding 10ul of a 25ug/ml stock solution of a secondary developing reagent such as Gt xRt IgG conjugated to a fluorochrome.
	Direct ELISA: 0.5-1.0ug/ml. The detection limit is ~1.5ng/well.
	Optimal dilutions to be determined by the researcher.
Hybridoma	Fusion of a mouse myeloma with B cells obtained from a rat immunized with purified, Sf 21-derived, recombinant mouse 4-1BB Ligand extracellular domain.
