Amsbio has announced the introduction of its latest aptamer kit for cell isolation and flow cytometry.
Aptamers are oligonucleotides or peptides that bind to a specific target molecule. They are useful in biotechnological and therapeutic applications because they offer molecular recognition properties that rival that of the commonly used biomolecule antibodies.
In addition to their discriminate recognition, aptamers offer advantages over antibodies as they can be engineered completely in a test tube, are readily produced by chemical synthesis, possess desirable storageproperties, and elicit little or no immunogenicity in therapeutic applications.
The AptoPrep cell isolation kit products from AMSBIO combine the specificity of aptamer to target cell with the convenience of isolation/elution of a particular cell from complex cell samples.
It is designed to deliver positive isolation in as little as 30 minuts. Mild and unique cell releasing technology allow isolation of bead- and aptamer-free cells in as little as an hour.
Incorporating bifunctional aptamer labeled with FITC and biotin the kits allow users to perform cell isolation and flow cytometry analyses simultaneously, further improving productivity.
Amsbio has also introduced a new range of dye-conjugated monoclonal aptamers specifically designed to monitor protein expression by flow cytometry with high specificity by minimising the background caused by non-specific binding.
Manufactured to ensure no batch-to-batch variation and compatible with all flow cytometers - AptoCyto flow cytometry aptamers facilitate quantitative, multi-parameter analysis of cell populations based on the expression of cell surface and/or intracellular molecules.
Based upon fluorescent dye-conjugated aptamers - AptoCyto flow cytometry kits are stable for several months at room temperature.
