Results from Dilute Electrolyte Additions and pH Changes in Agarose Gels

2 RESULTS FROM DILUTE ELECTROLYTE ADDITIONS AND pH CHANGES IN AGAROSE GELS 

Detailed inspection of Fig. 2.1 and Table 2.1 reveals that addition of 1 mM La3+ or 10 pm U022+ to the agarose gel medium had only slight effects, if any, on the number of bubbles produced by a given decompression, regardless of the gas used (ref. 49,139). Similarly, lowering the pH of the gel medium (from 7.4) to 6.0 (Fig. 2.1) or even to 4.0 (ref. 147) had little or no effect on bubble formation. 

Number of bubbles (four trials mean + S-E.M.) formed from rapid decompressions to atmospheric pressure of agarose samples (0.27 ml in volume) after saturation with either N9, CQ , or He. (Taken from ref. 139.)
