Ubiquitin Antibody

Western Blot: Ubiquitin Antibody [NB300-129]

Western Blot: Ubiquitin Antibody [NB300-129] - Analysis of HEK293 cell lysates using rabbit Ubiquitin antibody, dilution 1:5000 (Green), and mouse beta-Tubulin antibody, dilution 1:10000 (Red) used as a loading control. [1] protein standard (Red), [2] cells maintained in normal medium, [3] cells treated with proteasome inhibitor lactacystin (Lc) at 10uM for 16 hours. Lysed cells were lysed and the lysate subjected to electrophoresis on a 4-20% SDS-PAGE gel, then electrophoretically transferred to PVDF membranes. The smear detected above the 200kDa standard represents accumulations of ubiquitinated proteins in the Lc treated cells. The prominent band at ~8kDa corresponds to monoubiquitin.

Immunocytochemistry/ Immunofluorescence: Ubiquitin Antibody [NB300-129]

Immunocytochemistry/Immunofluorescence: Ubiquitin Antibody [NB300-129] - Analysis of HeLa cells stained with rabbit pAb to ubiquitin, NB300-129, dilution 1:1,000 in red, and costained with chicken pAb to vimentin, dilution 1:10,000, in green. The blue is DAPI staining of nuclear DNA. [A] Control HeLa cells maintained in normal medium, [B] HeLa cells treated with 10uM of the proteasome inhibitor lactacystin (Lc) for 24 hours. Proteasomal inhibition leads to formation of strongly ubiquitin positive cytoplasmic inclusions. Note the diffuse cytoplasmic ubiquitin staining in control cells and well defined ubiquitin positive inclusions in the Lc treated cells.
