Serine/threonine kinase which acts as an essential component of the MAP kinase signal transduction pathway. MAPK14 is one of the four p38 MAPKs which play an important role in the cascades of cellular responses evoked by extracellular stimuli such as proinflammatory cytokines or physical stress leading to direct activation of transcription factors. Accordingly, p38 MAPKs phosphorylate a broad range of proteins and it has been estimated that they may have approximately 200 to 300 substrates each. Some of the targets are downstream kinases which are activated through phosphorylation and further phosphorylate additional targets.

Immunofluorescence Antibody Validation Report for Anti-p38 Antibody (STJ94878)
1. ANTIBODY VALIDATION REPORT
Report Number 94878-a
Application Immunofluorescence
Model Number STJ94878
Antibody Name Anti-p38 antibody
Host Rabbit
Clonality Polyclonal
Clone ID NA
Species HUMAN Tissue LUNG
Image
Description
Immunofluorescence analysis of Human
lung tissue. 1: p38 Polyclonal
Antibody(red) was diluted at 1:200 (4
degree Celsius,overnight). 2: Cy3 labled
Secondary antibody was diluted at
1:300 (room temperature, 50min).3:
Picture B: DAPI(blue) 10min. Picture
A:Target. Picture B: DAPI. Picture C:
merge of A+B.
Primary Antibody Incubation
After blocking solution was removed a 1:200 primary antibody/PBS
solution was added on the slide, and incubated overnight at 4°C (a
small amount of distilled water was added into the incubation box to
prevent evaporation of antibody).
Secondary Antibody Incubation
slides were washed with PBS on a shaker for 5min, and repeated 3
times. Shortly after the slides were dried and corresponding
secondary antibody solution was added (HRP labelled), covering the
tissues, and incubated at room temperature for 50min.
DAPI Counter-Staining
slides were washed with PBS on a shaker for 5min, repeated 3 times
and then dried. DAPI staining solution was added inside the PAP
circles and incubated for 10 min at room temperature without light
exposure.
Mounting
Slides were washed with PBS on a shaker for 5min, and repeated 3
times. Shortly after slides were dried, anti-quench mountings were
used to mount slides.
Visualization
The slides were observed and placed under a NIKON inverted
fluorescence microscope (Ultra violet excitation 330-380nm,
emission 420nm; FITC green excitation 465-495nm, emission 515-
555 nm; CY3 red excitation 510-560nm, emission 590nm)
Immunofluorescence Protocol
Tissue Processing
Slides were incubated sequentially into: Xylene - 15min, Anhydrous
ethanol – 15 min, Anhydrous ethanol – 5 min, 85% alcohol – 5 min,
75% alcohol – 5 min & washed with distilled water – 5 min.
Antigen Retrieval
Tissue slides were incubated with citric acid (PH6.0) antigen
retrieval buffer, and microwaved for antigen retrieval (heated until
boiled and then stop heating) for 8min. Slides were then heated with
medium power for 7min. During this process slides are kept from
drying out. After cooling down at room temperature, slides were
washed with PBS on a shaker for 5min, and repeated 3 times.
Anti-Quench
shortly after slides were dried, a PAP pen was used to draw circles
around the tissues (to prevent draining of the antibody). Inside the
circles, anti-quench mountings were added and incubated for 5 min,
and then flushed with water for 10min.
BSA Blocking
Inside the circles, BSA was used to cover the tissue evenly, blocking
for 30min.
