Lack of a high-resolution structure for an entire tetraspanin is due to the lack of an expression system for preparation of the integral membrane protein in large quantity required for structural studies using protein X-ray crystallography or NMR spectroscopy.
Sample preparation by freeze-fracture has enabled observations of integral proteins embedded in membrane surfaces (Goodenough and Staehelin, 1971; Park and Pfeifhofer, 1969), but it cannot provide a 3D view of chloroplast architecture.

"Labor Day," Jason Reitman's romantic drama, and "The Lunchbox," a possible foreign-language Oscar submission from India, each features masterful scenes of food preparation integral to its story.
7 Clearly, sanitation, clean water, hand washing, and hygienic food preparation are integral to the control of cholera.
Since, integral membrane proteins can be hard to identify by MS due to poor peptide solubility we subjected the primary sequence of all identified proteins to hydropathy analysis by the method of Kyte and Doolittle [ 32] to estimate the total number of integral membrane proteins identified in our preparation.
Particular attention is focused on the preparation of biomembrane models capable of incorporating integral proteins in a functionally active state.
Valid dietary data across ethnic groups are few 55 but tomatoes are integral to the preparation of many common meals in the South Asian cuisine.
Section 6 introduces the special situation of integral membrane proteins in bicelles in general terms and section 7 describes the technical preparation of such samples.
Nowadays, engineering models used in training and learning simulators have become an integral part in the preparation of power plant operators and in postgraduate courses.
