Western blot analysis of extracts from UT-7 cells, untreated or treated with erythropoietin (EPO; 3 units/ml; 5 min) and from untreated HEL cells, using Phospho-Jak2 (Tyr1007) (D15E2) Rabbit mAb (upper) or total Jak2 (D2E12) Rabbit mAb #3230 (lower). HEL cells contain a V617F activating mutation in Jak2.

Reprobing of an existing membrane is a convenient means to immunoblot for multiple proteins independently when only a limited amount of sample is available. It should be noted that for the best possible results a fresh blot is always recommended. Reprobing can be a valuable method but with each reprobing of a blot there is potential for increased background signal. Additionally, it is recommended that you verify the removal of the first antibody complex prior to reprobing so that signal attributed to binding of the new antibody is not leftover signal from the first immunoblotting experiment. This can be done by re-exposing the blot to ECL reagents and making sure there is no signal prior to adding the next primary antibody.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.

Protocol Id: 10
Phospho-Jak2 (Tyr1007) (D15E2) Rabbit mAb detects endogenous levels of Jak2 when phosphorylated at Tyr1007. This antibody can also detect double phosphorylation at Tyr1007 and Tyr1008. Cross-reactivity may be observed with phosphorylated Jak3 and Tyk2.Species Reactivity:
Human, MouseSpecies predicted to react based on 100% sequence homology:
Rat, Monkey, Bovine
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr1007 of human Jak2.
Members of the Janus family of tyrosine kinases (Jak1, Jak2, Jak3, and Tyk2) are activated by ligands binding to a number of associated cytokine receptors (1). Upon cytokine receptor activation, Jak proteins become autophosphorylated and phosphorylate their associated receptors to provide multiple binding sites for signaling proteins. These associated signaling proteins, such as Stats (2), Shc (3), insulin receptor substrates (4), and focal adhesion kinase (FAK) (5), typically contain SH2 or other phospho-tyrosine-binding domains.
