This kit is for general cell membrane labeling. It has been characterized in a number of model systems and has been found to be useful for in vitro cell labeling, in vitro proliferation studies and short term, in vivo cell tracking. The half-life for elution of PKH2 from labeled rabbit red blood cells is 10-11 days. This slow elution may complicate interpretation of experiments assessing in vivo proliferation.

To examine the hypothesis that surface P-selectin-positive (degranulated) platelets are rapidly cleared from the circulation, we developed novel methods for tracking of platelets and measurement of platelet function in vivo. Washed platelets prepared from nonhuman primates (baboons) were labeled with...

Monocyte/macrophage-mediated cytotoxicity and antibody-dependent cellular cytotoxicity (ADCC) are slow processes, requiring cocultivation of effector and target cells for up to several days. Because of the high spontaneous release and possible reutilization of isotopic labels, the conventional radioactive release assays are...

Femoral head osteonecrosis (ON) is a serious complication of steroid administration. We examined whether implantation of autologous bone marrow-derived endothelial progenitor cells (EPCs) can augment neovascularization and bone regeneration in steroid-induced osteonecrosis of the femoral head. Forty 12-week-old male New-Zealand...

Cell-tracking reagents such as the green-fluorescent protein labeling dye CFSE and the red-fluorescent lipophilic membrane dye PKH26 are commonly used to monitor cell proliferation by flow cytometry in heterogeneous cell populations responding to immune stimuli. Both reagents stain cells with...

It has been shown that stromal-vascular fraction isolated from adipose tissues contains an abundance of CD34+ cells. Histological analysis of adipose tissue revealed that CD34+ cells are widely distributed among adipocytes and are predominantly associated with vascular structures. The majority...
