Benefits of semi-solid cloning:
• Individual cells are suspended in viscous medium and form physically separated, discrete colonies that are easily isolated.
• Monoclonal cell lines are isolated in less time using fewer resources compared with selection and cloning by limiting dilution.
• Diverse clones with a wide range of growth rates and productivities form discrete colonies in the viscous medium. As a result, rare and high-producing clones can be individually isolated more easily using simultaneous selection and cloning in semi-solid medium compared with selection in bulk liquid cultures.
• Recombinant proteins (animal component-free)
• Other ingredients

Frequently Asked Questions
Are there any selective agents in ClonaCell™-CHO ACF or ClonaCell™-CHO CD?
My cells grow fine in ClonaCell™-CHO ACF but I do not see colony growth in ClonaCell™-CHO CD. Why?
What medium do you recommend for the expansion of clones after selection in ClonaCell™-CHO ACF or ClonaCell™-CHO CD?
How many cells should I plate for cloning in ClonaCell™-CHO CD?
Is the serum in ClonaCell™-TCS medium heat inactivated?
Is there any IgG in ClonaCell™ TCS?
Can ClonaCell™-TCS be used with any cell line?
Why do I get more cells when I select my fusion in liquid medium rather than in methylcellulose-based semi-solid medium?
How do I thaw ClonaCell™ methylcellulose-based semi-solid medium?
How do I measure and dispense methylcellulose semi-solid medium?
My ClonaCell™ methylcellulose semi-solid medium appears runny. Why does this happen?
What is the optimal number of colonies per plate?
There are still bubbles in the media after I plate my cells. Do I need to disrupt the bubbles?
Do I ever need to re-clone cultures grown with ClonaCell™ semi-solid medium?
Once I pick the colonies and grow the cells in plates, will the residual methylcellulose interfere with characterization? For example, will I have problems doing an ELISA?
How important is the incubator humidity when culturing in methylcellulose-based medium?
Do I have to use 100 mm petri dishes or can I use other cultureware?
