Table 3. Recommended protein loads for IPG
strips
IIPPGG SSttrriipp LLeennggtthh
77 ccmm 1111 ccmm 1177 ccmm 1188 ccmm 2244 ccmm
Rehydration volume/strip 125 µl 185 µl 300 µl 315 µl 410 µl
Protein load
Silver stain 5–20 µg 20–50 µg 50–80 µg 50–80 µg 80–150 µg
Coomassie G-250 50–100 µg 100–200 µg 200–400 µg 200–400 µg 400–800 µg
Flamingo

,
SYPRO Ruby 2.5–75 µg 10–150 µg 25–300 µg 25–300 µg 40–600 µg
The suggestions made in Table 3 are a general rule of
thumb. Increased protein loads may be required for
micro-range IPG strips and for samples of higher protein
complexity.
