Conditional Knockout Mouse

Conditional knockout mouse models let you control where and when your gene of interest is knocked out. When you receive your new conditional line from ingenious,  it can be used in conjunction with hundreds of existing Cre lines for precise regulation. A conditional approach limits the knockout to your tissue of interest, avoiding potential embryonic lethality from constitutive knockout. Using Cre lines with drug-inducible activity expands your options to include temporal control of your knockout. There are many Cre’s to choose from such as tissue specific, inducible, and ingenious’ own Split-Cre for generating lines that are not currently available. The placement of loxP sites can be tricky when considering promoter and regulatory regions, ingenious experts can help alleviate this concern. Contact us today and our experienced scientists will analyze your gene of interest and develop a targeting strategy that is perfect for your research.

New technologies can enhance the utility of your conditional knockout (CKO) line.

ingenious’ proprietary No-Doubt Conditional Knockout™ system can activate expression of a reporter gene

in cells where your gene is knocked out independent of native gene promoter activity. 

Enhance your conditional model by adding a reporter to label affected cells, &  for visualizing where your gene has been knocked out on the cellular level.

To address the critical need of researchers to verify the loxP-mediated recombination of their conditional knockout models, and to do so in a reliable manner without increasing timelines, ingenious has developed the No-Doubt Conditional Knockout™ system.


Generating one mouse line with the potential for producing multiple derivative mouse models is a great way to save time and money. A knockout-first mouse model – with or without a reporter – can be used in gene rescue experiments and can also include conditional knockout potential.

Genistein and Breast Cancer Tumors

Genistein and Breast Cancer Tumors: Should Soy Consumption Be Halted in Breast Cancer Patients? According to recent scientific findings, the positive or negative effects associated with breast cancer patients consuming soy products can differ according to when the food was consumed. Patients who had already eaten soy products prior to their diagnosis might actually benefit

The Value of Knockout Mouse Models

Knockout Mice in Cushing’s Syndrome Research

New Insight on the Effects of the ARMC5 Gene on Patients Suffering from Cushing’s Syndrome Genetic experiments and knockout mice have recently helped scientists at the University of Montreal Hospital Research Centre (CRCHUM) gain new insight on the effects that eliminating a specific gene known as Armc5 can have in inducing particular ailments and predispositions
