Overview
Who said spheroids were hard to grow and use? The SpheroTribe kit is meant to facilitate life with spheroids. No matter the cells you are working with, you can form compact and uniform spheroids. You can also use it to handle any spheroid like a charm.
Once diluted in your culture medium of choice, our concentrated polymer-based solution promotes the formation and maintenance of circular 3D spheroids with an increased control over their size and shape. Combined with the 96-well round bottom plates and the large opening pipette tips provided in our kit, you have everything in hand to perform long-term routine culture of spheroids. Or to simply recover your spheroids from your plate and gently
isolate them for your desired downstream assays.
SpheroTribe is great to boost spheroid formation, notably for cells that are difficult to aggregate, or to increase the reproducibility of your functional assays, drug screening studies or in vivo implantation experiments.
SpheroTribe is compatible with any cell, any medium and any assay. It is easily washed away to perform downstream assays.

Features
Uniformity
Get spheroids of consistent size and circularity for greater reproducibility
Compactness
by increasing cell aggregation, SpheroTribe favors the formation and maintenance of
easy-to-handle
spheroids
Biocompatible
Composed of a biologically inert polymer, the solution will not affect your cell physiology, neither interfere with biological responses and can be washed away for downstream assays

Story
It all started in Bergen in the 2010s. I worked in the laboratory of Professor Rolf Bjerkvig, a precursor to the three-dimensional modelling of glioblastoma. When I returned to France, I wanted to import this technique and standardize it for cells that spontaneously grew into spheroids. We improved the Norwegian technique thanks to one discovery and one search: a viscous medium that we developed, and specific 96-well plates we found. But if the experiments became easy, taking the spheroids was less so. We pipetted with collagen, it was dirty and painful. Then we imagined cutting P200 cones to modify their tips. This allowed us to automatize everything and rely on a precise protocol to the point that when Agathe and Victor, from Idylle, came to the lab in Bordeaux for the first time, Agathe succeeded in the manipulation the first time. Despite this success, how many times have we had to do remote piloting for colleagues who were filming their movements in their lab! We needed a partner to standardize the protocol too. We were ripe for a collaboration with Idylle! Their entire team was very excited about our technology. The adventure together was so fast that I didn't have time to realize it had started that the transfer was already real and our technology had turned into SpheroTribe!
At first, we were all touched by Thomas's desire to share his discovery. Quickly, we were also fascinated by his level of investment and organization to carry out our common project. As an example, I was amazed by one fact: the day we arrived in his laboratory to show us the SpheroTribe protocol, we realized that he had been preparing spheroid plates just for us for 3 days. We just had to take them in hand, it was fantastic! This example is a good illustration of the relationship of trust between us, and I thank him here publicly for that!
