Hello, I have a data table like this one:

   value treatment time Protein.A Protein.B
1   mean    group1  24h      1.00     10.00
2   mean    group2  24h      2.00     11.00
3   mean    group3  24h      3.00     12.00
4   mean    group4  24h      4.00     13.00
5   mean    group5  24h      5.00     14.00
6   mean    group1  48h      6.00     15.00
7   mean    group2  48h      7.00     16.00
8   mean    group3  48h      8.00     17.00
9   mean    group4  48h      9.00     18.00
10  mean    group5  48h     10.00     19.00
11    sd    group1  24h      0.15      1.10
12    sd    group2  24h      0.36      1.87
13    sd    group3  24h      0.36      1.68
14    sd    group4  24h      0.72      2.21
15    sd    group5  24h      0.50      2.80
16    sd    group1  48h      0.60      2.40
17    sd    group2  48h      0.84      2.72
18    sd    group3  48h      1.36      2.89
19    sd    group4  48h      1.17      2.16
20    sd    group5  48h      1.90      2.85

For each protein, I want to make a bar chart with the x = treatment grouped by time, y = mean value of Protein A. Then, the error bar will be added by the sd value of protein A as well.
Is it possible to do it with ggplot2?
Can I make a loop to plot the bar chart for each protein? I do have 50 proteins that need to plot.
Thank you,
