    "EV pellets are invisible to the naked eye" I call differential centrifugation of sEVs a faith based protocol as you simply have to believe that there are exosomes in the invisible pellet and that your protein analysis or other protocols with validate your belief.

    This guy is focused on imaging rather than on science. He is doing a permanent nose and advertising himself, asking channels, TV to come and film his lab. I see fancy images, but nothing new in terms of concepts and science or biological rationale.

    Brilliant explaination, starting a project on EV in the next few months and I really needed some tips and tricks!

  • @mickensoneandre1686

    Cells actually uses acidification of exosomes to keep them close together and prevent them from repelling each other in the MVB because protein are more positively charge in acidic environments. However when exosomes are release into the extracellular environment they regain their repelling potential at pH 7.

  • @mickensoneandre1686

    Regarding the questions at the end, exosomes are naturally at 5.5 pH when they are in the MVB. So I highly doubt that acidification will affect the exosomes. Maybe microvesicles

    Thank you. We have recently been working with a company that is looking to develop a MSC-sEV treatment product for CNS injury and, as basic researchers, we have been struggling to understand what information we need to get in order to make that possible. This gave me a good overview of what is needed for a clinical trial approval.

    I learned a lot about LPs today, both in relationship to CVD and contamination of my sEV samples. Thank you for educating me. There was a lot that I did not know about the origin and life cycle of these particles which causes a lot of other data to now make sense to me.

    If a liposomal supplement smells strongly and distinctly of dish detergent... is it very likely that a detergent removal tequnique was used? If so, does this mean there is substantial solvent/detergent remaining left over and would that be advisable against consuming or distributing as a quality product? Thank you!

      Self-reporting is the only mechanism. We have no way to verify who has watched a given video or logged in to a given session. Even if we did, we would need support for the time required to do the verification and issue a certificate. This is currently a 100% volunteer, unpaid and unsupported effort.
