Protocol (CELLBANKER® series)
Freezing
For optimum results, cells for cryopreservation should be in log phase of growth. Similar or standard freezing protocols may be substituted.
IMPORTANT: Optimum protocol may change with the cell types.
Thawing
1. Cryopreservation analysis on hESC and iPS cells with STEM-CELLBANKER®
By Department of Clinical Science, Intervention and Technology, Karolinska Institute
Tested cell lines: HS293 & HS306 (hESC); ChiPSA (human iPS)
Freezing medium: STEM-CELLBANKER® vs Conventional freezing medium (10% DMSO in serum replacement containing culture medium)
Cell viability assessment: trypan Blue & calcein-esterase based live-dead assay
Result: Significantly higher cell viability was observed while cell pluripotency, normal karyotype and proliferation ability were maintained in HS293, HS306 and ChiPSA cell lines.
2. Cryopreservation analysis on Mesenchymal Stem Cells (MSCs) and Endothelial Progenitor Cells (EPCs) with STEM-CELLBANKER®.
By Regenerative Medicine Faculty, University of Tsukuba
MSCs EPCs
STEM-CELLBANKER® >95% >90%
Tested cell lines: Human UCB-derived MSCs and EPCs
Freezing medium: STEM-CELLBANKER®
Freezing protocol: Cell froze directly at -80℃ for 3days, transfer to -192℃ for 72 days.
Cell viability assessment: trypan Blue staining method.
Result: Cell viability as high as or more than 95% for MSCs and 90% for EPCs was observed while cell proliferation ability and differentiation ability were maintained in tested cells.
3. Cryopreservation analysis on Mouse ES cell (129SV)
By ZENOAQ cell engineering team
Tested cell line: 129SV (Mouse ES cell)
Freezing medium: CELLBANKER 1, 1plus, 2 and STEM-CELLBANKER®
4. Cryopresevation of mouse kidney tissue using STEM-CELLBANKER®
Mouse kidney was minced into about 5 mm square. The tissue samples were either immediately fixed with 10% formalin or cryopreserved with 1 ml of STEM-CELLBANKER at -80°C for one week. The cryopreserved samples were fixed with 10% formalin immediately after thawing. Paraffin sections of the both samples were stained with either H&E or anti-active caspase 3 antibody. Sign of necrosis or apoptosis was negligible in both of the fresh and cryopreserved tissue samples. Similar results were obtained in the cases of the tissue samples from a variety of mouse organs.
5. Preservation of mRNAs after cryopreservation of cells with STEM-CELLBANKER®
Total RNA was extracted from the cells of a mouse lung fibroblast cell line either immediately after harvesting or after cryopreservation with STEM-CELLBANKER at -80°C for one week and thawing. mRNA levels in the two samples were compared DNA microarray analysis, and the results showed that 93% of mRNAs was within the range of + 1.6-fold difference.
