The subject of the invention is the use of selected polyelectrolytes from the group of synthetic and natural polyelectrolytes for the cryopreservation of human and animal extracellular vesicles. The invention also relates to a method for the cryopreservation of these vesicles, which uses said poly electrolytes.

Use of polyelectrolytes as cryoprotectants and a method of cryopreservation with their use

A set of profiles for forming complex profiles comprises two profiles, namely a first profile () and a second profile (), adjoining each other and having walls surrounding a main chamber. Each profile () of the set has an outer shape which may be inscribed into a triangle, and has an inner wall () with a faying face () without protruding fragments. The faying faces () adjoining each other, after being coated with adhesive enable a joint to be created when the complex profile is discussed, however, in the case of the set of the profiles they are considered to be contact surfaces. After adjoining the first profile () and the second profile () by attaching the first faying face () to the second faying face () in order to create a complex profile (), a first outer surface () of first side walls () and a second outer surface () of second side walls () are situated outside of the complex profile and an angle between the first outer surface () and the second outer surface () equals to a sum of a first angle (&#x3b1;) between the first faying face () and the first outer surface () of the first side wall () of the first profile () and a second angle (&#x3b2;) between the second faying face () and the second outer surface () of the second side wall () of the second profile ().
