DescriptionRabbit polyclonal to MK2 (phospho T334)
Detects endogenous levels of MK2 only when phosphorylated at threonine 334 (human) and threonine 320 (mouse and rat). The immunogen sequence used to produce ab63378 is 90% identical to the corresponding region of MK3, therefore ab63378 may cross react with human MK3 but this has not been confirmed.

Purification notesThe antibody was affinity-purified from rabbit antiserum by affinity chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
Our Abpromise guarantee covers the use of ab63378 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC/IF||Use a concentration of 1 µg/ml.|
|WB||1/500 - 1/1000. Detects a band of approximately 46 kDa (predicted molecular weight: 46 kDa).|
|IHC-P||1/50 - 1/100.|
FunctionIts physiological substrate seems to be the small heat shock protein (HSP27/HSP25). In vitro can phosphorylate glycogen synthase at 'Ser-7' and tyrosine hydroxylase (on 'Ser-19' and 'Ser-40'). This kinase phosphorylates Ser in the peptide sequence, Hyd-X-R-X(2)-S, where Hyd is a large hydrophobic residue (By similarity). Mediates both ERK and p38 MAPK/MAPK14 dependent neutrophil responses. Participates in TNF alpha-stimulated exocytosis of secretory vesicles in neutrophils. Plays a role in phagocytosis-induced respiratory burst activity.
Tissue specificityExpressed in all tissues examined.
Sequence similaritiesBelongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family.
Contains 1 protein kinase domain.
modificationsPhosphorylated and activated by MAP kinase.

Immunohistochemical analysis of paraffin-embedded human breast carcinoma tissue labelled with ab63378 at 1/50 dilution. Right hand panel was treated with immunising phosphopeptide.
ICC/IF image of ab63378 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab63378, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
