It is possible to observe precipitate in HBSS buffer. The precipitate does not have an impact on the use of this kit, nor the results that are gathered from its use.
What is the difference between the original CyQuant assay and the CyQuant NF assay?
The original CyQUANT assay provides sensitive detection of cells over a 1000-fold linear dynamic range. In this assay, a freeze-thaw cell lysis step is required to facilitate the interaction of the CyQUANT GR dye with DNA. The CyQUANT NF assay avoids this freeze-thaw step by using a DNA binding dye in combination with a plasma membrane permeabilization reagent. The CyQUANT NF protocol requires only aspiration of growth medium (for adherent cells), replacement with dye binding solution, incubation for 30-60 minutes, and then measurement of fluorescence in a microplate reader. The assay is designed to produce a linear analytical response from at least 100-20,000 cells per well in most cell lines in a 96-well microplate.
Do you offer any products to measure neuronal cell health?
PrestoBlue Cell Viability Stain and CyQUANT Cell Proliferation Assay Kit can be used. We also offer a Neurite Outgrowth Staining Kit (Cat. No. A15001). More information about our different assays for neuronal cell health can be found here (https://www.thermofisher.com/us/en/home/life-science/cell-analysis/neuroscience/neuronal-cell-health-assays.html).

Functional symbiosis between endothelium and epithelial cells in glomeruli.
Authors:Hirschberg R, Wang S, Mitu GM,
Journal:Cell Tissue Res
PubMed ID:17999087
'In some capillary beds, pericytes regulate endothelial growth. Capillaries with high filtration capacity, such as those in renal glomeruli, lack pericytes. Glomerular endothelium lies adjacent to visceral epithelial cells (podocytes) that are anchored to and cover the anti-luminal surface of the basement membrane. We have tested the hypothesis that podocytes ... More
Flex-Hets differentially induce apoptosis in cancer over normal cells by directly targeting mitochondria.
Authors:Liu T, Hannafon B, Gill L, Kelly W, Benbrook D
Journal:Mol Cancer Ther
PubMed ID:17575110
'Flex-Het drugs induce apoptosis in multiple types of cancer cells, with little effect on normal cells. This apoptosis occurs through the intrinsic mitochondrial pathway accompanied by generation of reactive oxygen species (ROS). The objective of this study was to determine if direct or indirect targeting of mitochondria is responsible for ... More
Cytosolic delivery of membrane-impermeable molecules in dendritic cells using pH-responsive core-shell nanoparticles.
Authors:Hu Y, Litwin T, Nagaraja AR, Kwong B, Katz J, Watson N, Irvine DJ,
Journal:Nano Lett
PubMed ID:17887715
'Polycations that absorb protons in response to the acidification of endosomes can theoretically disrupt these vesicles via the "proton sponge" effect. To exploit this mechanism, we created nanoparticles with a segregated core-shell structure for efficient, noncytotoxic intracellular drug delivery. Cross-linked polymer nanoparticles were synthesized with a pH-responsive core and hydrophilic ... More
Decrease of endogenous vascular endothelial growth factor may not affect glioma cell proliferation and invasion.
'Vascular endothelial growth factor (VEGF) is abundantly produced by glioma cells especially glioblastoma, the most malignant form of astrocytoma. VEGF, a well known angiogenic factor, acts in a paracrine fashion on endothelial cells to develop tumor vasculature. However, recent studies have found that several tumor cells express VEGF receptors, and ... More
