La mezcla de nutrientes F12 de Ham (F-12) fue diseñada para una placa de célula única libre de suero de células de ovario de hámster chino (CHO). El F-12 ya se ha utilizado para el crecimiento libre de suero de cultivos de CHO además de para el crecimiento complementado con suero de otras células de mamíferos, incluidos condrocitos y células epiteliales de la próstata de rata. Ofrecemos una gran variedad de modificaciones de F-12 para una gama de aplicaciones de cultivos celulares. Busque la formulación adecuada mediante la herramienta de selección de medios.

Este F-12 de Ham se modifica del siguiente modo:
Con
• L-glutamina
• Rojo de fenol

Está disponible la formulación completa.

Uso de F-12
En comparación con otros medios basales, el F-12 contiene una variedad más amplia de componentes, incluidos cinc, putrescina, hipoxantina y timidina. El F-12 no contiene proteínas ni factores de crecimiento. Por lo tanto, el F-12 requiere una suplementación, normalmente con suero fetal bovino (SFB) al 10 %. El F-12 utiliza un sistema de tampón de bicarbonato de sodio (1,176 g/l) y, por lo tanto, requiere un entorno con un 5-10 % de CO2 para mantener el pH fisiológico.

Sistema de fabricación y calidad conforme a las buenas prácticas de fabricación actuales
Para mantener la continuidad de la cadena de suministro, fabricamos F-12 en dos instalaciones separadas; una ubicada en Grand Island, Nueva York, y la otra en Escocia, Reino Unido. Ambos sitios cumplen los requisitos de producción según las buenas prácticas de fabricación actuales, cuentan con la certificación ISO 13485 y están registrados en la FDA como fabricantes de dispositivos médicos.

Preguntas frecuentes

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.
