ICC/IF image of ab105389 stained SKNSH cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab105389, 1/200 dilution) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43μM.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Pericyte Marker (CD31, NG2, PDGFR beta, CD146, Nestin) Antibody Panel - Human (AB254020)

Immunohistochemical staining of paraffin embedded human spleen with purified ab32570 at a working dilution of 1/50. The secondary antibody used is ab97051, a HRP-conjugated goat anti-rabbit IgG (H+L), at a dilution of 1/500. The sample is counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control, and is shown in the inset.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Pericyte Marker (CD31, NG2, PDGFR beta, CD146, Nestin) Antibody Panel - Human (AB254020)

IHC image of CD146 staining in human aorta formalin fixed paraffin embedded tissue section, 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 20 mins. The section was then incubated with ab24577, 5μg/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.

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.

Western blot - Pericyte Marker (CD31, NG2, PDGFR beta, CD146, Nestin) Antibody Panel - Human (AB254020)

All lanes : Anti-Nestin antibody [SP103] (ab105389) at 1/100 dilution

Lane 1 : Wild-type HAP1 whole cell lysate

Lane 2 : NES knockout HAP1 whole cell lysate

Lysates/proteins at 20 μg per lane.

Predicted band size : 177 kDa

Lanes 1 - 2 : Merged signal (red and green). Green - ab105389 observed at 300 kDa. Red - loading control, ab18058, observed at 117 kDa.

ab105389 was shown to specifically react with NES in wild-type HAP1 cells as signal was lost in NES knockout cells. Wild-type and NES knockout samples were subjected to SDS-PAGE. ab105389 and ab18058 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/100 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
