Table 3.
Long spacings (dL) and correlation length (ξ) determined from SAXS patterns and short spacings (dS) determined from p-bromo benzoic acid (WAXS) patterns of DPPC without or with FTC, TDF, and FTC+TDF (3:2 w/w) in the Lβ′ and Lα phases.
| Lipid Bilayers in the Absence or Presence of Drugs | Long-Spacing Values (SAXS) 1 | Short-Spacing Values (WAXS) | ||||
|---|---|---|---|---|---|---|
| dL 1 (Å) | ξ | dS (Å) | dS (Å) | |||
| Lβ′ | Lα | Lβ′ | Lα | Lβ′ | Lβ′ | |
| DPPC | 62.91 | 65.15 | 1084 | 1018 | 4.25 | 4.11 |
| DPPC + FTC | 51.80 | 54.21 | 41 | 24 | 4.21 | 4.11 |
| DPPC + TDF | 62.70 | 68.14 | 96 | 688 | 4.24 | 4.14 |
| DPPC + FTC + TDF | 53.36 | 53.55 | 41 | 42 | 4.19 | 4.11 |
1 The spacings were calculated for the first reflection order Bragg peak.
