Our purified lyophilized exosomes are obtained from different biological sources including cell culture supernatant, human plasma, serum and urine. Isolation is performed by a combination of ultracentrifugation and microfiltration procedures, and subsequent quantification/validation for overall protein content and particle number by NTA with Nanosight.
Background Info:
Exosomes are small endosome derived lipid nanoparticles (50-120 nm) actively secreted by exocytosis by most living cells. Exosome release occurs either constitutively or upon induction, under both normal and pathological conditions, in a dynamic, regulated and functionally relevant manner. Both amount and molecular composition of released exosomes depend on the state of a parent cell. Exosomes have been isolated from diverse cell lines (hematopoietic cells, tumor lines, primary cultures, virus infected cells) as well as from biological fluids in particular blood (e.g. serum and plasma from cancer patients) and other body fluids (bronchoalveolar lavage fluid, pleural effusions, synovial fluid, urine, amniotic fluid, semen, saliva etc). Exosomes have pleiotropic physiological and pathological functions and an emerging role in diverse pathological conditions such as cancer, infectious and neurodegenerative diseases.
Product Type:
Lyophilized exosomes
Storage Temp:
Store up to 3 years at 4°C >>> Storage of reconstituted exosomes: -20°C for up to one month or -80°C for up to 6 months. Avoid repeated freeze-and-thaw cycles.
Lyophilized Exosome Standards from MSC from human adipose tissue (for research use only)
Additional Info:
Lyophilization is an ideal method for long-term storage of exosomes and microvesicles. It does not alter the stability of exosome proteins and nucleic acids, in comparison to other storage methods, including storage of fresh EVs at -20°C. Lyophilized EVs and microvesicles are easy to ship and stable for long term storage (up to 36 months).
Application Details:
Assay calibration. Control (spike-in) for exosome quantification. Protein marker analysis using different techniques. Extraction and analysis of exosome nucleic acid. Standardized positive controls for immunocapture performance evaluation. Flow cytometry. Electron microscopy.

Mesenchymal stem cells, also known as marrow stromal cells, are defined as a self-renewing population of adherent, bone-marrow-derived multipotent progenitor cells with the capacity to differentiate into several mesenchymal cell lineages. Bone marrow-derived MSCs are multipotent adult stem cells with multilineage differentiation potential, including the ability to differentiate into bone (osteoblasts), tendon, cartilage (chondrocytes), fat (adipocytes), fibroblasts, endothelial cells, and smooth and cardiac muscle cells.

Product Quality Control:
Rigid quality control testing is performed for each batch (both cell donors and cell cultures). Cultured cells are tested for cell identity, purity, potency, viability and suitability for the intended use.
Before cryopreservation cultured MSCs (P2-P3) are characterised by flow cytometry analysis for identity by a comprehensive panel of markers [CD73/CD90/CD105 (positive) and CD14/CD34/CD45/HLA-DR (negative)] as proposed by the ISCTMSC committee position statement, 2006.
A multilineage differentiation assay into adipogenic and osteogenic directions is performed for each MSCs batch expanded in vitro. In addition, all donors and cell cultures have been screened for the absence of the following infectious agents: HIV-1/2, HBV, HCV, HSV1, HSV2, CMV, EBV, HHV6, Treponema pallidum, Toxoplasmagondii, Chlamydia trachomatis, Ureaplasma urealyticum, Ureaplasma parvum and microbial contaminants (bacteria & fungi,Mycoplasma hominis and Mycoplasma genitalium).
MSC cultures genetic stability is verified by karyotype evaluation (GTG banding).
