water-soluble and detergent-soluble membrane proteins. All the points for the water-soluble proteins lie on a sigmoid curve (except fibrinogen, which has different behavior as aresult of its asymmetrical shape). The membrane proteins clearly fall outside the calibration curve for water-soluble proteins, so that the Stokes radii estimated from this curve are high by 10–30%. HimmelandSquire(84)foundsignificantimprovementinthedetermination of protein molecular weight using denaturing conditions. Their study reconciles the size parameters of proteins and random coils by determining F(v) in Eq. (17): F(v) ¼ V1=3 E V 1=3 T V 1=3 i V 1=3 i MuchlesserrorforthemolecularweightdeterminationisfoundwhenplottingF(v) ! (17) vs. MW 1/3 than KD vs. logMW, RS vs. MW 1/3 ,or K 1=3 D vs. MW1/3 .Tarvers and Church (91), working with TSKgel G3000SW columns, utilized both native and denaturedproteinstocompareplotsofF(v)vs.MW 1/3 ,RSvs.erf (1 F(v)),andRS vs.erf (1 KD)andconfirmedplotsofF(v) vs.MW 1/3 providedabetterestimate of protein molecular weight. The method of Himmel and Squire (for example, F(v) vs. MW 1/3 )has been used to produce linear curves with native proteins (92–94), denatured proteins (95), and,independently,globular proteins (96). Denaturing gel filtration with 0.1% sodium dodecyl sulfate (SDS) or 6M guanidine hydrochloride results in better resolution, increased accuracy,and an extended linear range. This provides asimple, rapid, and sensitive means of separating protein mixtures and determining protein molecular weights that deviateonly5–7%fromreportedvaluesmeasuredbygelfiltration,sedimentation equilibrium, or SDS–polyacrylamide gel electrophoresis (97). On TSKgel G3000SW(Fig.13),thelinear partofthecalibration curvefor proteins denatured inguanidinehydrochlorideextendsfrommolecular weight9000to43,000.Using the same column, the calibration curve for SDS-denatured proteins is linear from 9000 to93,000, andnondenaturing conditionsprovide alinear curvefrom 30,000 to 93,000 with no resolution below 30,000. Similar work by Kato (58) provided the optimum separation ranges presented in Table 7. Good agreement on protein behavior was seen between the various studies for G3000SW columns. 4 SECONDARY RETENTION Schmidt et al. (98) showed how retention volumes of globular proteins varied on silica-based diol bonded phase columns depending on the pH and ionic strength of the mobile phase and their effective charge. Because most proteins elute within the interstitial pore volume, size exclusion is the dominant effect; other possible mechanisms are secondary order effects (99). Pfankoch et al.
