How big are microbubbles?
In particular, we currently use polydisperse microbubbles that are 16–18 um in diameter. Learn more about microbubbles technology.
What are microbubbles made of?
Akadeum’s microbubbles are made of thin shells of glass with a gaseous core. Learn more about microbubble technology.
How many cells can a microbubble lift?
When isolating fully dispersed cells (such as in a Ficoll or leukopheresis PBMC prep), we have seen microbubbles carrying as many as 4 cells. Cells…
What is the Separation Buffer?
Ca2+, Mg2+ free Dulbecco’s PBS containing 2mM ETDA, 0.09% sodium azide, and 0.5% bovine serum albumin (BSA). BSA must be biotin free as to not…
Does Akadeum have a recommendation for biotin free BSA?
Millipore Sigma Bovine Serum Albumin – Product #A7030
Can Akadeum microbubbles be analyzed by flow cytometry?
Yes. Analyzing samples of microbubbles or microbubbles bound to cells can be performed but high concentrations of microbubbles have been found to clog the SIP…
My spleens are very large, is it possible to process samples containing >100 million cells in a single separation?
No. Samples in excess of 100 million cells should be divided and multiple separations performed. The cells can be recombined afterward. This is a result…
What if my samples are small (<10 million cells)?
When processing samples that are less than 10 million white cells/splenocytes, Akadeum recommends the following protocol changes: Replacing the provided 5 mL centrifuge tubes with…
Are Akadeum microbubble enriched samples compatible with flow cytometry?
Yes. Residual microbubbles in samples will not interfere with flow cytometry. Microbubbles are larger than many cell types and have very bright side scatter so…
Can I culture the isolated cells after isolation with Akadeum microbubbles?
Yes. After removal of the microbubble layer, the remaining cell pellet can be resuspended in any desired buffer and cultured or analyzed with other methods.
I am using an Akadeum mouse kit, do I have to lyse the red cells?
Lysing red cells is recommended to increase purity. The antibody cocktails contain a TER119 antibody to capture and remove red cells. However, depending on the…
Can I do back to back isolations to improve purity?
Yes, but any improvement in purity will be accompanied by additional loss of desired cells.
Why is mixing volume 50% of the total volume?
This ensures adequate opportunity for the microbubbles to find lower abundance cell types that are targeted. Using a higher percentage (ex. 70%) will perform similarly,…
I’m having trouble aspirating the microbubbles, what can I do?
Please watch the video demonstrating the aspiration of microbubbles. Working with microbubbles can take a bit of practice.
What if there are a lot of microbubbles remaining (stuck to the sides of the tube) after aspiration? Is this a problem?
As these microbubbles should only contain cells that are targeted for removal, they should not cause any issues. However, if you wish to remove them,…
Can I decrease the biotin antibody incubation time?
No. Lower incubation times at 4°C will result in lower purity.
Can I perform the biotin antibody incubation at room temperature for a shorter time?
Akadeum has not determined if shorter room temperature incubations will change product performance so it is not recommended at this time.
After sitting in the refrigerator, all the microbubbles have separated out of solution. Is there something wrong?
This is normal. The solution will need to be mixed well before every use.
How do I know if the microbubbles are mixed enough before using them?
The microbubbles should be a homogenous white solution. Rocking the vial, a brief vortex, or mixing with a pipet can all help. After mixing, check…
How fast is too fast for mixing the microbubbles?
Trituration should be performed at approximately 0.5 to 1 stroke per second. See the video at www.Akadeum.com for a demonstration.
I’m worried about trituration impacting my cells, is there an alternative mixing method?
Akadeum has found slow mixing by trituration to be the most effective and quickest method for mixing microbubbles with cells.
I don’t have low retention pipet tips; can I use standard tips?
Low retention tips are not required but more microbubbles will adhere to standard tips. This may impact isolation performance.
I don’t have access to a swinging bucket rotor centrifuge, can I still use Akadeum microbubbles?
Microbubbles will still rise to the top in a fixed rotor centrifuge however the microbubble layer will not be even. This can make aspirating more…
I don’t have an aspirator/vacuum available in my lab, can I still use Akadeum microbubbles?
Aspiration is the best/easiest way to remove the microbubble layer after centrifugation. Pipetting off the bubble layer is not very effective and pipetting the cell…
How are Akadeum kits shipped?
Cell Separation Kits are shipped on ice packs with overnight delivery.
How should I store components?
Separation Buffer, microbubbles and antibody cocktail should be stored at 4 degrees Celsius.
