"description": "Synchrotron SAXS data from solutions of allergen Hev b 8 bound to murine IgE in 20 mM Tris, 50 mM NaCl, pH 8.4 were collected on the B21 beamline at Diamond (Didcot, UK) using an EigerX 4M-Detrics detector at a sample-detector distance of 3.7 m and the wavelength of 0.95 A. In-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A 70.00 μl sample at 6.2 mg/ml was injected at a 0.60 ml/min flow rate onto a GE Superdex 200 Increase 10/300 column at 15°C. 620 successive 3 second frames were collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.\r\nThe molecular weight of a murine IgE, considering glycosylation, is approximately 190-198 kDa (protein 180 kDa + 10-18 kDa glycosylation). This estimate is an approximation; the actual molecular weight can vary depending on the specific glycosylation patterns and modifications of the IgE molecule. In this way the estimated MW for the complex (including the the Profilin with his TAG) is approximately 240 kDa.",
