Description
Kaighn’s Modification of Ham’s F-12-K Medium
Background
Kaighn’s Modification of Ham’s F-12-K Medium is a modified version of Ham’s F-12 medium. originally, Ham’s F-12K (Kaighn’s) was used for primary cells such as human oocytes and hepatocytes, as well murine and chicken liver cells in a lower serum environment. but, however, recently this media is used for a much larger variety of cells.
Moreover, Ham’s F-12K (Kaighn’s) Medium contains a variety of components not found in older media, such as putrescine thymidine, hypoxanthine, zinc, and higher levels of all amino acids and sodium pyruvate.
Ingredients:
F-12K Medium also contains:
– Low level of glucose (1.26 g/ liter)
– Sodium bicarbonate (2.5 g/L) (if higher than 5% CO2 is used, a higher % of sodium bicarbonate is needed).
– Additionally, PurMa Biologics also offers F-12K Medium with different level of sodium bicarbonate : 1.5 g/L (Cat # P3S057108) as well as, 3.7g/L (Cat # P3S032108)
– 2 mM L-glutamine (292 mg/L)’
– A higher concentration of amino acids, vitamins, inositol and choline are present in this medium.
Why PurMa Biologics? Why we stand behind our Cell Culture Media:
Our products are the outcome of 30 years of experience in cutting edge cell and tissue culture science. Also, we utilize %99 pure amino acids. This will significantly increase the consistency among your experiments, and the result of your lab compared to other laboratories working on the same issues.
We routinely manufacture over 1500 media, which is the most comprehensive collection of cell and tissue culture media. Considering the highest quality, our prices are extremely reasonable.
Application of Ham’s F-12K:
This media has elements that prevent clumping, therefore, it is ideal for culturing primary as well as commercial cell lines, for instance normal and neoplastic leukocytes, HeLa, Jurkat, MCF-7, PC12, PBMC, astrocytes, carcinomas, bone marrow, and hybridoma cells.

Background
Williams' E Medium - Max is a commonly used media for Mammalian cell culture.Advantages
The advantages of Williams' E Medium - Max over Williams' E Medium are:
- Higher PH Capacity
- Moreover, it contains 4 mM L-Alanyl-L-Glutamine (0.869 g/L) instead of L-Glutamine and therefore:
- Possess longer shelf life.
- More importantly, minimizes toxic ammonia build-up.
- Significantly improves cell viability and growth.
- Remains stable across a wide range of temperatures.
- Improves the culture of primary cells.
Mechanism
Although L-glutamine is a vital amino acid, it degrades, resulting in the generation of toxic ammonia and pyrrolidine carboxylic acid. One way to minimize L-glutamine degradation in media is to gradually add these amino acids to your cell culture. However, keeping track of time to keep the amount of L-glutamine at the same level is tedious, if not impossible. Alternatively, L-alanyl-L-glutamine can be used because it is much more stable in aqueous solutions. More importantly, it does not easily degrade and gradually releases aminopeptidases. As a result, L-glutamine and L-alanine are then used by the cells for protein production in the TCA cycle. In addition to our Max formulation products, we manufacture PurMaTM GluaSup (Cat# P3S210 559) is a combination of L-alanyl-L-glutamine which prevents degradation of L-glutamine.Contents
Williams' E Medium - Max contains:
- 5 mM sodium pyruvate
- High glucose (4.5g/L)
- Non-Essential Amino Acids
- 3.7 g/L Sodium Bicarbonate; PurMa Biologics Manufactures several types of William’s E Medium based on the amount of Sodium Bicarbonate and HEPES (PH capacity)
- Phenol Red

Background
Minimum Essential Media (MEM) In Hanks’ Buffer is a modification of Basal Medium Eagle . It was originally developed by Harry Eagle for specific requirements of certain subtypes. Additionally, it includes higher concentrations of amino acids which is more suitable for cultured mammalian cells. Moreover, PurMa Biologics manufactures MEM with Earle’s buffer for use in a CO2 incubator, or with Hanks' salts for use without CO2.PurMa™ MEM media in Hank’s buffer includes Hank's buffer
Hanks buffer, it contains:- Potassium Chloride
- Potassium Phosphate, monobasic
- Sodium Bicarbonate
- Sodium Chloride
- Sodium Phosphate, dibasic
Additionally, MEM in Hanks’ Buffer contains:
- Low level of glucose (1.00 g/ liter)
- Sodium bicarbonate (0.35 g/L). If , however, higher than 5% CO2 is used, a higher % of sodium bicarbonate is needed.
- 2 mM L-glutamine (292 mg/L)
Why PurMa Biologics? Why we stand behind our cell culture media
Our products are the outcome of 30 years of experience in cutting edge science. We routinely manufacture over 1500 media. We have the most comprehensive collection of cell and tissue culture media.

MEM has been used for the cultivation of a wide variety of cells grown in monolayers attached or in suspension cell lines such as HeLa, BHK-21, 293, HEP-2, HT-1080, MCF-7, and fibroblasts as well as primary rat astrocytes. MEM contains no proteins, lipids, or growth factors. Therefore, MEM requires supplementation, commonly with 10% fetal bovine serum (FBS).Formulation

Background
PurMaTM Advanced Eagle’s Minimal Essential Medium (A-EMEM) contains components that allow for a 60–90% reduction in FBS supplementation. More importantly, using synthetic components such as recombinant insulin, albumin, and transferrin increase consistency. This results in less variation amongst lot-to-lot serum changes. In A-EMEM, L-Alanyl-L-Glutamine is used as the source of glutamine. Additionally, reducing FBS requirements lowers the cost of cell culture experiments.Contents
Advanced EMEM Contains:
- includes all twenty essential and non-essential amino acids with higher concentrations than regular and MAX formulations.
- A-EMEM incorporates elements that significantly reduce the need for a serum for cell culture.
Crucial Ingredients:
- PurMaTM Human Transferrin (Holo): prevents Improper iron storage and delivery in cell culture systems which is a major contributor to oxidative stress and protein damage.
- PurMaTM Insulin Recombinant
- Trace of other elements which mimic the elements in fetal bovine serum.

Background
Basal Medium Eagle (BME) in Hanks’ Buffer originally developed by Harry Eagle. Moreover, this media is one of the most widely used of all synthetic cell culture media. Markedly, BME is the predecessor of Eagle’s Minimum Essential Medium (MEM) and Dulbecco’s Modified Eagle’s Medium (DME). PurMa Biologics presently manufactures BME with Earle’s for use in a CO2 incubator, or with Hanks' (HBSS) salts for use without CO2.Ingredients
As the composition, this media contains HBSS buffer HBSS buffer contains:- Potassium Chloride
- Potassium Phosphate, monobasic
- Sodium Bicarbonate
- Sodium Chloride
- And lastly, Sodium Phosphate, dibasic
Application
PurMa Biologics manufactures 117 types BME in HBSS buffer. This media has been successfully used for variety of suspension and adherent mammalian cells, including HeLa, BHK-21, 293, HEP-2, HT-1080, MCF-7, fibroblasts as well as primary rat astrocytes.Formulation
