Scientific Data Images for Tmp21/p23 Antibody (PSH01-41)

Tmp21/p23 Antibody (PSH01-41)

Immunohistochemistry: Tmp21/p23 Antibody (PSH01-41) [NBP3-33031]

Immunohistochemistry: Tmp21/p23 Antibody (PSH01-41) [NBP3-33031] - Immunofluorescence analysis of paraffin-embedded human breast tissue labeling Tmp21/p23 with Rabbit anti-Tmp21/p23 antibody (NBP3-33031) at 1/200 dilution.

The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 10% negative goat serum for 1 hour at room temperature, washed with PBS, and then probed with the primary antibody (NBP3-33031, green) at 1/200 dilution overnight at 4 ℃, washed with PBS. Goat Anti-Rabbit IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. Nuclei were counterstained with DAPI (blue).

Immunohistochemistry: Tmp21/p23 Antibody (PSH01-41) [NBP3-33031] - Immunohistochemical analysis of paraffin-embedded human breast tissue with Rabbit anti-Tmp21/p23 antibody (NBP3-33031) at 1/200 dilution.

The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (NBP3-33031) at 1/200 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Immunocytochemistry/ Immunofluorescence: Tmp21/p23 Antibody (PSH01-41) [NBP3-33031]

Immunocytochemistry/ Immunofluorescence: Tmp21/p23 Antibody (PSH01-41) [NBP3-33031] - Immunocytochemistry analysis of HeLa cells labeling Tmp21/p23 with Rabbit anti-Tmp21/p23 antibody (NBP3-33031) at 1/250 dilution.

Cells were fixed in 4% paraformaldehyde for 20 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 5 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Rabbit anti-Tmp21/p23 antibody (NBP3-33031) at 1/250 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI.

Beta tubulin (red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 594) was used as the secondary antibody at 1/1,000 dilution.

Background: Tmp21/p23

TMP21 is a ubiquitously expressed protein that is involved in vesicular targeting and protein transport. More recent experiments have shown that it is also a component in the presenilin complex and modulates the gamma-secretase, but not the epsilon-secretase cleavage activity of the amyloid precursor protein. The presenilin complex is composed of the proteins APH1, nicastrin, and PEN2 in addition to presenilin-1. Together, these proteins cleave the amyloid precursor protein at what is known as the gamma- and epsilon-sites, and can lead to the accumulation of the Abeta cleavage product that is associated with Alzheimer's disease. Co-immunoprecipitation experiments using antibodies against these proteins also yielded TMP21, indicating that TMP21 may play a role in the regulation of this complex. Suppression of TMP21 expression by siRNA in transfected cells caused increased gamma-secretase activity and Abeta production, but not epsilon-secretase activity, demonstrating that TMP21 can modulate gamma-secretase activity.
