Cell transfer

The research of cell mobility is wildly used in the tumor invasion and metastasis. Tumor metastasis is one of distinct features of malignant tumor biology. Cancer cells manifest strong mobility during certain stage of cancer metastasis. For example, cancer cells break away from original foci, invading into neighboring tissue and passing through vessel wall into blood circulation, then thread out of the vessel into secondary position. Therefore, research about cell’s mobility exerts great importance in comprehending the mechanism of cancer cell’s invasion and transfer.

Cell scratch

Cell scratch is one of method to assay tumor cell’s mobility. It takes reference from in vitro cell wound healing model, making scratch injury on the monolayer cells cultivated in vitro, then observing the mobility of cancer cells by means of medication or interference.

Induced transition

Put Transwell chamber into Culture Plate (inboard chamber is called upper chamber and inboard Culture Plate is called lower chamber). Upper and lower chamber are separated by a polycarbonate membrane. We plant cells in the upper chamber. As polycarbonate equips permeability, components in the lower culture medium can affect cells of the upper chamber. Therefore, we can study the impact of components in the lower medium on the cell’s growth and mobility. Commonly used two types of this experiment are regular transwell chamber(transfer) and matrix paved transwell chamber(invasion).

Stable Cell Line Services for Assay Development

In vitro assays based on gene engineered cells play crucial roles in modern drug discovery processes. Especially for GPCRs and ion channels, multiple trans-membrane proteins, the cell-based assays are dominant in chemical library screening. There are many stable cell lines and assay techniques are developed to model human bodies. With expertise on cell line generation and assay development, Elabscience offers your Gene-to-Assay solution for your drug discovery project.

Elabscience has developed a Ready-to-Assay GPCR & Ion Channel Cell Line Collection which is available as product for your order. If you can’t find the stable cell lines of your interests, please choose the service to customize your stable cell lines with our available assays or other assays upon your specifications.

Service Package

Elabscience utilizes 2-round selection strategy for GPCR and ion channel stable cell line generation upon different applications. To reduce the cost and timeline, Elabscience chooses HTS-compatible fluorescence- or luminescence-based assays to screen stable clones in the 1st round selection. In 2nd round selection, radioisotope- and electrophysiology-based assays are available upon your applications. For nuclear receptors, transporters, and other targets which have no ready HTS-compatible assays, Elabscience offers mRNA or protein level assays as alternative solutions.

In addition, Elabscience can develop a new assay upon your specifications. Please feel free to contact us for technique support.

Flow cytometric detection

Flow cytometry is a laser based, biophysical technology employed in cell counting, sorting, biomarker detection and protein engineering, by suspending cells in a stream of fluid and passing them by an electronic detection apparatus. It allows simultaneous multiparametric analysis of the physical and/or chemical characteristics of up to thousands of particles per second.

Flow cytometry is routinely used in the diagnosis of health disorders, especially blood cancers, but has many other applications in basic research, clinical practice and clinical trials. A common variation is to physically sort particles based on their properties, so as to purify populations of interest.

Years of solid experience and unique expertise in custom protein expression and purification services render Elabscience to help you break the bottlenecks in protein expression and purification.
