Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD28 antibody [EPR22076] - BSA and Azide free (AB243557)

Immunohistochemical analysis of paraffin-embedded human multiple myeloma tissue labeling CD28 with ab243228 at 1/2000 dilution, followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP). Membranous staining on human Multiple Myeloma cells. (PMID : 7522634) is observed. Counterstained with hematoxylin.

Secondary antibody only control : Used PBS instead of primary antibody, secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP).

Perform heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0).

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab243228).

Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized Jurkat (human T cell leukemia T lymphocyte) cells labeling CD28 with ab243228 at 1/50 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing membranous staining in Jurkat cells. The nuclear counter stain is DAPI (blue).

Counterstained with ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor^® 594) at a 1/200 dilution (red).

The negative control is the secondary antibody only.

Immunoprecipitation - Anti-CD28 antibody [EPR22076] - BSA and Azide free (AB243557)

CD28 was immunoprecipitated from 0.35 mg Jurkat (human T cell leukemia T lymphocyte) whole cell lysate with ab243228 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab243228 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/5000 dilution.
Lane 1 : Jurkat whole cell lysate 10 μg (Input).
Lane 2 : ab243228 IP in Jurkat whole cell lysate.
Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab243228 in Jurkat whole cell lysate.
Blocking/Dilution buffer : 5% NFDM/TBST.
Exposure time : 30 seconds.

The target band ranging between 37kDa-48kDa is consistent with what has been described in the literature (PMID : 2825196). Minor band below 15kDa is likely to be an isoform.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab243228).
