How to use CellCover
CellCover stabilizes cells in suspension, biopsies, or tissue without cell lysis, keeping cells close to in vivo morphology. CellCover is compatible with morphological analyses and staining procedures, including immunocytochemistry, immunohistochemistry, and flow cytometry, among many other downstream applications.
A unique and special feature of CellCover is the ability to perform additional molecular analysis on cells that have already been analyzed on a morphological or molecular level: DNA (e.g. PCR), RNA (e.g. RNA seq or single cell RNA-seq) or protein (e.g. protein modification analysis, protein sequencing, or proteomic analysis) can be isolated for subsequent applications after initial immunolabeling, immunohistochemistry, immunocytochemistry, or flow cytometry analyses.
Application of CellCover is simple. Remove cell culture medium, apply CellCover and incubate for two minutes. Then proceed with your standard protocol.
CellCover can be used in the following applications (and many other!):
- Batch and single cell analysis
- Flow cytometry / FACS
- DNA Sequencing
- Protein Sequencing
- RNA Sequencing (RNA Seq)
- Single Cell RNA Sequencing
- Northern Blotting
- Western Blotting
- Many more applications

How it works
CellCover was developed for fast “one step” stabilization of biomolecules in life science research. CellCover is a non-toxic formulation, a formaldehyde alternative designed to protect the status of DNA, RNA, and protein expression and gene expression in human and animal cells and solid tissues, including tumors and cultured cells (adherent, suspension, spheroids). DNA, RNA, proteins and cell morphology are all protected.
As soon as cells are exposed to CellCover their metabolic state is frozen without applying low temperatures- the liquid frozen effect. Synthesis and turnover of bio-molecules are stalled. This includes instant disruption of cellular degradation pathways, making cell fixation by CellCover very fast. Chemical degradation is inhibited with CellCover as well, leading to exceptional protein stabilization and protein fixation, as well as RNA fixation and DNA fixation. CellCover acts as an DNA and RNA stabilizer and shield, which is beneficial e. g. for analysis by flow cytometry or in NGS or RNA seq approaches. CellCover is a key initial step for successful experiments in genome analysis, transcriptome analysis, and proteomic analysis.
Cells grown on almost any substrate can be treated with CellCover by liquid freezing to maintain in vivo morphology without chemical crosslinking of biomolecules during cell fixation.
Cell morphology is preserved, allowing for accurate visualization of molecule location. DNA, RNA, and proteins are also stabilized and preserved when performing cell fixation with CellCover, allowing for effective downstream experiments in genomics, transcriptome analysis, and proteomics.
High RIN Values
With CellCover performing RNA fixation and acting as an RNA stabilizer, RNA degradation is inhibited, leading to great results in RNA sequencing or single cell RNA seq or single cell sequencing experiments. Material destined for a biobank is kept without altering expression due to environmentally induced gene expression changes. Even integrity of high molecular weight RNA is protected (e.g. precursor rRNA, which are normally degraded after applying commonly used standard procedures) – and there is no need to hurry! You can store your sample in CellCover at 4°C and isolate RNA later.
Protein expression analysis has no limits. Study protein modification and proteomics with CellCover taking care of protein fixation and protein stabilization. CellCover is a safe formaldehyde alternative fixation, with formalin sensitive epitopes readily accessible for antibodies in immunohistochemistry experiments.

With CellCover fixation, excellent sample quality is maintained with no time given for changes in the sample to occur. Not only perfectly fixed RNA is retained, but typical cellular morphology is also maintained and the antigens are readily accessible for a wide variety of applications (IF, IHC etc.).
What our Customers are saying
„CellCover preserved nucleic acids of cells underwent immunofluorescence staining and imaging. Cell fixation with CellCover preserved more nucleic acids compared to formaldehyde and methanol fixation for our microscopy experiments.“
D. Wu, Diagnostics Company in US, Cancer Immunology
“We wanted to collect clear RNA from Neutrophil which has low RNA and short survival. After collecting Neutrophils, we fixed with cellcover immdiatly. It was good for collecting quality of RNA because it can use for RNA sequences.”
Tohoku Medical and Pharmaceutical University, Division of Medical Biochemistry
“I prefer CellCover to other fixatives such as PFA as it does not require a wash to remove. We are also able to extract more RNA per cell when compared to other fixation methods.”
Josh, Diagnostics Company in US, Oncology
“Since the cells are fixed, we do not always have to perform quickly for staining with antibody, FACS, and RNA extraction after collecting cells. In other words, it is good for starting our experiment at our convenience.”
Kyushu University – Graduate School of Medical Sciences, Department of Anatomy and Cell Biology
“Mostly I used CellCover for sorting of brain microgrial cell and neuron. Regarding CellCover, recently one paper came out from our laboratory where I used CellCover.”
