Table 1.

Protein (mg/mL) present in sample supernatant as assayed by UV absorbance spectroscopy following ‘elution’ treatment. All samples originally contained 0.2 mg/mL protein in the presence of 0.5 mg/mL Aluminum. Where a dash is present no sample was analyzed. Error was estimated at approximately 0.05 mg/mL.
