Western Blotting (WB), Flow Cytometry (FACS), Enzyme Immunoassay (EIA)
特异性
This antibody recognizes VASP only, when Ser239 is phosphorylated, a site preferred by cGMP-dependent protein kinase (PKG) but also used by cAMP-dependent protein kinase (PKA). The antibody does not crossreact with the non-phosphorylated form of VASP nor with unrelated serine-phosphorylated proteins. Therefore, antibody VASP-22E11 is able to monitor the phosphorylation state of VASP serine 239 as well as PKA activity.

ELISA: Use at 0.05 μg/mL. Western Blot: 0.5 μg/mL for HRPO/ECL detection. Recommended blocking buffer: Casein/Tween 20 based blocking and blot incubationbuffer AS00002BU-N or AS00002BU-L. Flow Cytometry. Included Positive Control: Cell lysate from Forskolin-treated HepG2 cells (See Protocols formore details). Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.
实验流程
Positive Control Cell Lysate: HepG2 Forskolin treatedFormat: Lyophilized cell lysate from HepG2 cells. Reconstitution: Restore by addition of 200 µl H2O. After complete solubilization add 200µl 2x SDS-PAGE sample buffer, mix and incubate at 90°C for 5 min. Application: The positive control cell lysate is recommended for immunoblot applications. 20 µl of positive control cell lysate correspond to ca. 20. 000 cells. Use 20 µl/lane (mini gel) for HRPO/ECL detection of the target proteins. Please NOTE: The lyophilized cell lysates conatin SDS and are not recommended forapplications with native proteins such as in immunoprecipitation.

VASP (vasodilator stimulated phosphoprotein) plays an important role in ANF / NO / cGMP Protein kinase and cAMP / cAMP Protein kinase signalling pathways. VASP is expressed in almost all human and animal cell lines, particularly high concentrations are found in thrombocytes, vascular smooth muscle cells and fibroblasts. In cultured cells VASP is associated with focal contacts, cell-cell-contacts, microfilaments and dynamic membrane regions such as the leading edge. In vitro binding data show that VASP binds to profilin, zyxin, vinculin, and the Listeria spp. surface protein ActA. Functional evidence indicates that VASP is a crucial factor involved in the enhancement of actin filament formation.Synonyms: Vasodilator-stimulated phosphoprotein
