Monoclonality Analysis


Identification service of gene transfer position in CHO cell

Multicolor FISH and mapping FISH are combined to identify the chromosome constitution of CHO cells and the integrated position of the target gene gene, such as an antibody. Quality control, such as hot spot search in CHO cells and confirmation of monoclonality, is possible.
