CD28 was immunoprecipitated from 0.35 mg EL4.IL-2 (mouse lymphoma T lymphocyte) whole cell lysate with ab242124 at 1/30 dilution. Western blot was performed on the immunoprecipitate using ab242124 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366) was used for detection at 1/5000 dilution.
Blocking and dilution buffer and concentration: 5% NFDM/TBST.
Exposure time: 15 seconds.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab242124).
Immunohistochemical analysis of paraffin-embedded mouse spleen tissue stained for CD28 using ab242124 at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) Ready to use. Positive staining in periarterial lymphatic sheath of mouse spleen (PMID: 7489738). Counter stained with Hematoxylin.
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) Ready to use.
The section was incubated with ab242124 for 30 mins at 37℃. Immunostaining was performed on a Leica Biosystems BOND® RX instrument.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (a242124).
Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
