摘要:
Short oligopeptides are provided which are capable of binding to the epidermal growth factor receptor on the surface of human tumor cells. Methods for using the peptides as targeting moieties in more complex compositions, such as conjugates of cytoxins, and/or structures, such as liposomal structures, for the purposes of drug delivery are also provided.

摘要:
Polypeptides comprising EGFR extracellular domains I-III capable of forming dimeric EGF-binding proteins are provided. The dimeric construct of the invention is useful in applications where high affinity EGF binding is desired and can be used to select agents capable of binding to native EGFR in the presence of EGF.

A lamp cover containing phosphor for providing white light emission is disclosed. The lamp cover is comprised of a light-partial-reflective cap structure providing the outer surface of the lamp cover, wherein the light-partial-reflective cap structure is composed of a plurality of light transparent layers and a plurality of vacuum layers that are stacked in an alternating manner from outside to inside, a supporting transparent cap structure providing the inner surface of the lamp cover, and a phosphor mixed structure mechanically supported by the outer surface of the supporting transparent cap structure, wherein the outer surface of the phosphor mixed structure is adjacent to the most inner vacuum layer of the light-partial-reflective cap structure. Once the lamp cover is combined with a phosphor exciting light source, the light-partial-reflective cap structure partially prevents phosphor exciting light from escaping from the lamp cover by using Fresnel reflection.
