Ham's F-12K (Kaighn's) Medium is a modification of Ham's F-12 Nutrient Mixture. Ham's F-12K (Kaighn's) Medium was developed for primary human hepatocytes, as well as for some rat and chicken liver cells in a reduced serum environment.

This F-12K (Kaighn's) Medium is manufactured as follows:

WithWithout
• L-glutamine• HEPES
• Phenol Red 


The complete formulation is available.

Using Ham's F-12K
Ham's F-12K (Kaighn's) Medium contains many components not found in traditional basal media, such as putrescine, thymidine, hypoxanthine, zinc, and higher levels of all amino acids and sodium pyruvate. These additions allow the medium to be supplemented with very low levels of serum or defined components, for some cell types. Ham's F-12K (Kaighn's) Medium contains no proteins or growth factors, and is therefore often supplemented with growth factors and Fetal Bovine Serum (FBS). The FBS concentration must be optimized for each cell line. Ham's F-12K (Kaighn's) Medium uses a sodium bicarbonate buffer system (2.5 g/L), and therefore requires a 5–10% CO2 environment to maintain physiological pH.

Frequently asked questions (FAQs)

How long can I keep my media after supplementing with serum?

Generally speaking, media can be used for up to three weeks after supplementation with serum. There are no formal studies to support this, but it is the rule of thumb used by our scientists.

My medium was shipped at room temperature but it is supposed to be stored refrigerated. Is it okay?

We routinely ship media that require long-term storage in the refrigerator at room temperature. We have done studies on representative media formulations to show that media can be at room temperature for up to a week without a problem.

How can I remove mycoplasma contamination from my cell culture medium?

Very often mycoplasma contamination cannot be removed from the culture so it should be discarded. You may have a unique culture that you prefer not to discard and would like to try to clean it. Ciprofloxacin and Plasmocin have reportedly been used for this application. If interested in a protocol or directions for use, check with the antibiotic supplier or published literature. Note that mycoplasma are very difficult to remove from culture and spread easily so the treated cultures should be quarantined until clear of mycoplasma, and your laboratory should be thoroughly cleaned.

I see a decrease in growth of my culture. What should I do?

Try changing the medium or serum. Compare media formulations for differences in glucose, amino acids, and other components. Compare an old lot of serum with a new lot. Increase initial cell inoculums. Lastly, adapt cells sequentially to new medium.

My cells are not adhering to the culture vessel. What should I do?

This can occur if cells are overly trypsinized. Trypsinize for a shorter time or use less trypsin. Mycoplasma contamination could also cause this problem. Segregate your culture and test for mycoplasma infection. Lastly, check for attachment factors in the medium.
