Cell Line Monoclonality Identification Services

KMD Bioscience has devoted itself to the research of cell biology technology for many years. We have an experienced team of scientific research experts, an experimental team with exquisite experimental skills, a perfect cell culture platform, complete experimental instruments and experimental conditions, built a complete FISH technical service platform, and accumulated a lot of successful experience. With solid professional technology, we can provide customized services from probe design to cell monoclonal origin identification, and strive to solve problems for customers in an efficient and cost-effective way.

In order to ensure the uniformity of the quality of recombinant drugs, the relevant institutions stipulated the development of cell lines when IND was declared.





* <0.5 cell/well or higher standard after two rounds of limited dilution

* Images demonstrating single cells are desirable

* <0.5 cell/well after two rounds of limited dilution

* Two rounds of Clonpix

* <0.5 cell/well after one limited dilution + cell photography

* FACS + cell photography

* FACS + one round of limited dilution

* Clonpix + one round of limited dilution


Clonality is considered to reduce the heterogeneity of cell bank. The commonly used methods of obtaining monoclonal, such as limited dilution method, ClonePix, flow cytometry and so on, are time-consuming and expensive, and there are many uncertainties in the process of cell culture. Different from probability calculation and statistics, fluorescence in situ hybridization is used to detect whether cells are from a single source, and the results are visual and more convincing.
