In our recent publication entitled, ‘Quantification of the efficacy of collagen cross-linking agents to induce stiffening of rat sclera’ published on 5 April 2017 (doi:10.1098/rsif.2017.0014), we regret to inform you that we have identified a minor error in table 1, the original version of which is reproduced below.
| stiffening agent | concentration (mM) | concentration (% w/v in PBS) |
|---|---|---|
| genipin | 0.25, 0.50, 1.0, 7.5, 15, 30 | 0.06, 0.11, 0.23, 1.7, 3.4, 6.8 |
| glyceraldehyde | 10.0, 30.0, 62.5, 125 | 0.90, 2.7, 5.7, 11 |
| methylglyoxal | 3.5, 7.0, 14 | 0.25, 0.50, 1.0 |
Specifically, the values in the third column of this table are too large by a factor of 10. A corrected version of the table appears as follows:
| stiffening agent | concentration (mM) | concentration (% w/v in PBS) |
|---|---|---|
| genipin | 0.25, 0.50, 1.0, 7.5, 15, 30 | 0.006, 0.011, 0.023, 0.17, 0.34, 0.68 |
| glyceraldehyde | 10.0, 30.0, 62.5, 125 | 0.09, 0.27, 0.056, 1.1 |
| methylglyoxal | 3.5, 7.0, 14 | 0.025, 0.05, 0.10 |
Fortunately, all experiments were carried out with the correct concentrations, i.e. the third column in the above table was calculated after the fact, so that this error does not affect any results reported in the paper. The authors regret this oversight.
