Table 1 Viable cell number of 2E3-O cells after frozen-thawing process.
From: Cryopreservative solution using rakkyo fructan as cryoprotectant
Cryopreservative solution | Mean degree of polymerization | Viable cell number (×106) |
|---|---|---|
30 w/v% rakkyo fructan | 390 | 99.5 |
30 w/v% inulin (low molecular weight) | 16 | 64.5 |
10 w/v% inulin (high molecular weight) | 19 | 5.0 |
1 w/v% levan | 1000 | 0.2 |
Positive control | - | 111 |
