Calcium phosphate transfection method is a simple, time efficient and relatively inexpensive way to introduce DNA into cells in stable cell lines such as HEK293T, CHO and BHK cells. This method works best in cell lines that are highly transformed and adherent and this technique requires few manipulative steps and maintains high levels of reproducibility from experiment to experiment.

Captor
is a label-free, microfiltration system for isolation, enumeration, and retrieval of circulating tumor cells (CTCs). Captor
system utilizes a proprietary Clear Cell
CTChip®
technology based on sophisticated fluid dynamics and myriads of crescent-shaped microwells to ensure capturing of CTCs while leaving other whole blood constituents to flow through.The elegant and simplistic design maximizes CTCs isolation efficiency, purity, and function by preserving CTCs surface integrity, allowing retrieval of the viable cells in their native state. This video shows you how to install Captor

Hemocytometer or Cell Counting Chamber is frequently used to count cell numbers such as cell density of cultured cells in research labs and blood count and sperm count in clinical labs. For counting of attached cells, cells are trypsinized, mixed with a dye (Trypan Blue), loaded onto a hemocytometer and then counted under a microscope.

Cell freezing is the procedure to store cells for future studies. The storage of cells ensures that you have back-up cells in case of contamination or loss of cell supply. This video shows the procedure for using "CoolCell". The "CoolCell" is an alcohol-free freezing container which provides the ideal freezing rate close to minus 1°C/minute required for successful cryopreservation of cells.

Competent cells are those that possess more easily altered cell walls that DNA can be passed through easily. Because DNA is hydrophilic, it will not normally pass through membrane. In order to make these cells readily incorporate foreign DNA, they must first be made "competent" to take up foreign DNA.

In competitive ELISA, unlabeled antibody is incubated in the presence of its antigen. Then these bound antibody/antigen complexes are then added to an antigen coated well. After washing, unbound antibodies are removed. The more analytes in the sample, the less antibodies will be able to bind to antigens in the well. The signal is then detected using labeled secondary antibodies and the decrease in signal is compared to a control. The major advantage of a competitive ELISA is the ability to use crude or impure samples and still selectively bind any antigen that may be present.

Cre-Lox recombination is a special type of site-specific recombination. The Cre protein is a site-specific DNA recombinase. It can catalyze the recombination of DNA between specific sites in a DNA molecule. These sites, known as loxP sequences, contain specific binding sites for Cre that surround a directional core sequence where recombination can occur. It is often used in the generation of knockout and conditional knockout animals.
