Anti-Ki67 抗体 [SP6] (ab16667)

ab16667 staining Ki67 in wild-type HAP1 cells (top panel) and Ki67 knockout HAP1 cells (bottom panel). The cells were fixed with 100% methanol for 5 minutes, permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1 hour. The cells were then incubated with ab16667 at 1/250 dilution and ab195889 at 1/250 dilution (shown in pseudo colour red) overnight at +4°C, followed by a further incubation at room temperature for 1 hour with Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed (ab150081) secondary antibody at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.

Immunostained tissue sections from control-, AT1-, and MLL-LNs

Proliferating cells (Ki67+, brown) were seen in lymph follicles (presumably B-lymphocytes) and in para-follicular areas (presumably T-lymphocytes) in control-LNs. In AT1-LNs, the para-follicular areas dominated, and contained most of the proliferating cells. In MLL-LNs, the para-follicular regions appeared to contain less proliferating cells than in AT1-LNs.

Frozen sections of rat lymph node tissue were stained for Ki67 using ab16667 in immunohistochemical analysis. DAB staining.

Effect of newborn anoxia and PD156707 on proliferation and binucleation of neonatal cardiomyocytes

A representative image of cardiomyocytes stained with α-actinin (green), Ki-67 (red), and Hoescht (blue).

4% paraformaldehyde-fixed, Triton X-100 permeabilized rat cardiomyocytes were stained for Ki67 using ab16667 at 1/100 dilution in ICC/IF.

ab16667 staining Ki67 (red) in transgenic mouse spinal cord tissue sections (depleted of oligodendrocytes) by Immunohistochemistry (PFA perfusion fixed frozen sections). Tissue samples were fixed by perfusion with paraformaldehyde, permeablized with 0.5% Triton X-100 and blocked with 10% serum for 1 hour at 25°C; antigen retrieval was by heat mediation in 10 mM citrate buffer, pH 6, for 20 minutes at 97°C in a water bath. The sample was incubated with primary antibody (1/300 in PBS + 0.1% Triton X-100 + 1% serum) at 25°C for 16 hours. An Alexa Fluor^® 594-conjugated donkey anti-rabbit IgG (H+L) polyclonal (1/700) was used as the secondary antibody. Counterstained with Iba1 (green) a marker for microglia and DAPI.

ab16667 staining Ki67 in common marmoset spleen by immunohistochemistry (formalin/PFA-fixed paraffin-embedded sections). Tissue was fixed with formaldehyde and a heat mediated antigen retrieval step was performed using citrate buffer. Samples were then blocked with 1% BSA for 10 minutes at 21ºC followed by incubation with the primary antibody for 2 hours at 1/100. A biotin-conjugated goat anti-rabbit polyclonal was used as secondary antibody at a 1/250 dilution.
