Target of this antibody:
Alternative names of antibody target:
Signal transducer and activator of transcription 4, stat -4
Membrane receptor signaling by various ligands induces activation of Jak kinases which then leads to tyrosine phosphorylation of the various Stat transcription factors. Stat1 and Stat2 are induced by IFN-α and form a heterodimer which is part of the ISGF3 transcription factor complex. Althoμgh early reports indicate Stat3 activation by EGF and IL-6, it has been shown that Stat3β appears to be activated by both while Stat3α is activated by EGF, but not by IL-6. Highest expression of Stat4 is seen in testis and myeloid cells. IL-12 has been identified as an activator of Stat4. Stat5 is activated by prolactin and by IL-3. Stat6 is involved in IL-4 activated signaling pathways.
Clonality of antibody:
This antibody reacts with:
Human, mouse, rat
Synthetic peptide surrounding amino acid 732 of rat Stat4
Concentration of antibody:
Form of antibody:
Formulation of this antibody:
100 µg (0.5 mg/ml) affinity purified rabbit polyclonal antibody in phosphate-buffered saline (PBS) containing 30% glycerol, 0.5% BSA, and 0.01% thimerosal.
This antibody has been succesfully tested for use in following methods:
Western blotting (0.5-4 µg/ml). However, the optimal concentrations should be determined individually. The antibody recognizes ~97 kDa Stat4 in samples from human, mouse, and rat origins. A ~60 kDa band can also be detected, presumably to be the cleavage fragment of Stat4.
Shelf time: 12 months in temp.: -20 deg.C
How to handle this antibody:
The antibody solution should be gently mixed before use.
This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.
If you buy Antibodies supplied by Biovision they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
