HA720140F_1.jpg Fig1: Immunocytochemistry analysis of MCF-7 cells labeling Cytokeratin 19 with Rabbit anti-Cytokeratin 19 antibody (HA720140F) at 1/100 dilution.

Cells were fixed in 100% methanol for 10 minutes, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes, and then blocked with 1% BSA for 30 minutes at room temperature. Cells were then incubated with Rabbit anti-Cytokeratin 19 antibody (HA720140F) at 1/100 dilution in 1% BSA overnight at 4 ℃. Nuclear DNA was labelled in blue with DAPI.

Beta tubulin (M1305-2, red) was stained at 1/200 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 594, HA1126) were used as the secondary antibody at 1/800 dilution.

Cells were fixed in 100% methanol for 10 minutes, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes, and then blocked with 1% BSA for 30 minutes at room temperature. Cells were then incubated with Rabbit anti-Cytokeratin 19 antibody (HA720140F) at 1/50 dilution in 1% BSA overnight at 4 ℃. Nuclear DNA was labelled in blue with DAPI.
HA720140F_3.jpg Fig3: Immunofluorescence analysis of paraffin-embedded human breast tissue labeling Cytokeratin 19 (HA720140F).

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 Cytokeratin 19 (HA720140F, iFluor™ 488) at 1/100 dilution overnight at 4 ℃, washed with PBS. DAPI was used as nuclear counterstain.
HA720140F_4.jpg Fig4: Flow cytometric analysis of SK-Br-3 cells labeling Cytokeratin 19.

Cells were fixed and permeabilized. Then incubated for 1 hour at +4℃ with Cytokeratin 19 (HA720140F, red, 1ug/ml). Unlabelled sample was used as a control (cells without incubation with primary antibody; black).
