(1) = The number of samples tested depends on the number of replicates/sample performed. For example, if 6 replicates/sample are performed, then 16 samples can be analyzed on a single 96-well plate. These samples, however, do not have to performed on the same day.
(2) = The total culture volume for AllColonies™ Multi and CAMEO™-96 depends on the number of replicates/sample performed. If 4 replicates are required, 0.6mL total volume would be prepared, while for 6 replicates, 0.8mL would be prepared.
(3) = Culture time depends on the the state of fractionation or purification of the source cells, cell population tested and species.
(4) = Instrument calibration is performed using the ATP controls included with the assay kit.
(5) = Standardization implies performing a standard curve. ATP standards are included. ColonyGro™ and CAMEO™-4 or any other methylcellulose colony-forming assay from competitors do not include standards or controls and can not be standardized. "Standardized media" does not make an assay "standardized".
6 = Since AllColonies™ Multi and CAMEO™-96 include standards and controls that allow the results to be compared to measurement assurance parameters every time an assay is performed, proficiency testing is also performed automatically at the same time as the instrument is calibrated and the assay standardized.
7 = Measurement assurance parameters are included in the Instruction Manual.
8 = Validation parameters are included in the Instruction Manual. Since standards and controls are included with these assays, validation can be performed in-house. ColonyGro™ and CAMEO™-4 as well as all other methylcellulose colony-forming assays from competitors, do not include standards and controls and, therefore, cannot be standardized or validated.

The graph to the left shows a cell dose response comparison between ColonyGro™ for the primitive hematopoietic stem cell population, CFC-GEMM 1, and the nearest MethoCult™ equivalent population detected with H4435 media. The difference between the growth factors is given in the table above, but whereas the CFC-GEMM 1 growth factor cocktail contains Flt3-Ligand and thrombopoietin (TPO), to induce the production of megakaryocytes, MethoCult™ H4435, contains neither of these components. Consequently, MethoCult™ H4435 cannot produce megakaryocytes, and therefore does not stimulate the production of primitive stem cells and cannot be designated as a CFC-GEMM population; MethoCult™ H4435 actually stimulates a more mature stem cell population.
- 100mL of ColonyGro™ Reagent
- Sufficient for 44 duplicate samples
- 2.5ml total volume prepared/sample
- 0.25ml sample cell suspension volume required
- 1ml plated in 2 x 35mm Petri dishes
ColonyGro™ is a slightly different formulation that (a) allows it to be easier and more accurately dispensed, (b) allows more samples to be assayed, (c) allows greater cell interaction that is important for cell growth and, (d) allows more rapid growth so that colonies can be detected between 10-12 days instead of 14 days
Do ColonyGro™ reagents contain the same growth factor cocktails as other methylcellulose reagents?
Yes. In some cases, ColonyGro™ actually includes more growth factors. For example, the formulation for CFC-GEMM 1 includes thrombopoietin (TPO) to stimulate the production of megakaryocytes. This is not the case for other methylcellulose CFC-GEMM culture reagents produced by other companies who falsely claim that CFC-GEMM can be detected. If TPO is not included, no megakaryocytes will be produced. What is being detected are colonies that contain granulocytes, erythroid cells and macrophages.
How many samples can be used with ColonyGro™?
One of the many advantages of ColonyGro™ is that from a 100mL bottle, 44 samples can be assays as opposed to about 30 for other methylcellulose reagents. The different formulation of methylcellulose combined with the lower total culture volume for duplicate replicates, allows more samples to be assayed. This in turn means that the user can run more samples for about the same price as other methylcellulose reagents.
How many cell populations can be detected using ColonyGro™?
Depending on the species, ColonyGro™ is available to detect up to 19 different cell populations.
What species can be used with ColonyGro™?
Human, non-human primate, dog, rat mouse, horse, sheep and pig.
Why does Preferred Cell Systems recommend using a positive displacement pipette to dispense methylcellulose?
Methylcellulose is notoriously difficult to dispense because it is so viscous. Using a syringe and needle adds to the inaccuracy of the assay because inaccurate volumes are dispensed. By using a positive displacement pipette, methylcellulose can be dispense much more accurately, resulting in lower variation. However, like all pipettes, a positive displacement pipette must be professionally calibrated to dispense accurately.
Why use ColonyGro™ instead of other methylcellulose reagents?
Besides all the reasons given above, ColonyGro™ is competitively priced, so that more samples can be assayed for a similar price. In short, the investigator is getting more for their money.
Can ColonyGro™ be used in the cell processing laboratory?
Yes. Preferred Cell Systems has developed ColonyGro™ with the exact same growth factor cocktails as found in all MethoCult™ reagents used in the cell processing laboratory.
Can ColonyGro™ be used as a cell proliferation assay?
No. Although cell proliferation is needed to produce colonies, the assay cannot measure cell proliferation. The CFC or CFU assay is a differentiation assay because the colonies are left to grow until the cells comprising the colony can be identified as belonging to a specific lineage. This can only occur when the cells have differentiated.
