Immunocytochemistry/Immunofluorescence analysis of Ramos+/-pervanadate(1mM, 30min), Ramos + pervanadate(1mM, 30min) + LP labelling Syk (phospho Y323) with ab62338 at a dilution of 1:1000 dilution (2.53ug/ml). Cells were fixed with 4% Paraformaldehyde and permeabilized with 0.1% tritonX-100. ab150077 Goat anti rabbit IgG(Alexa Fluor® 488) (1:1000) was used as the secondary antibody. The cells were co-stained with ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) 1:200 (2.5 μg/ml). Nuclei counterstained with DAPI (blue). Control: PBS instead of the primary antibody.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab62338).

This data was developed using the same antibody clone in a different buffer formulation (ab62338).
Immunohistochemical analysis of paraffin-embedded human lymph node tissue sections labeling Syk with purified ab62338 at 1/100 dilution. ImmunoHistoProbe one step HRP Polymer (ready to use) was used as the secondary antibody. Sections were counterstained with Hematoxylin.
Antigen retrieval was heat mediated antigen retrieval using citrate buffer, pH 6.0).

 IHC image of Syk (phospho Y323) staining in a section of formalin-fixed paraffin-embedded normal human tonsil* performed on a Leica BOND^TM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab70328, 0.05ug/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Dot blot analysis of Sky (pY323) peptide (Lane 1), Syk (unmodified) peptide (Lane 2), labelling Syk (pY323) with ab62338 at a dilution of 1/1000. Peroxidase conjugated goat anti-rabbit IgG (H+L) was used as the secondary antibody at a dilution of 1/2500.

Blocking and dilution buffer: 5% NFDM/TBST.

Exposure time: 10 seconds.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab62338).

This Flow cyt data was generated using the same anti-phospho Syk Y323 antibody clone, EP573-4, in a different buffer formulation (cat# ab62338).

Flow Cytometry analysis of U937 (human monocyte histiocytic lymphoma) treated (red)/untreated (green) with 1mM pervanadate for 30 minutes with purified ab62338 at 1/2500 dilution. The secondary antibody was Goat anti rabbit IgG (Alexa Fluor^® 488) at 1/2000 dilution. A Rabbit monoclonal IgG (Black) was used as the isotype control and cells without incubation with primary antibody and secondary antibody (Blue) were used as unlabeled control.
