    摘要: A sensor device is formed from a metal film having a plurality of openings, a sensor material positioned within each of the openings, a light source that emits light having a first wavelength, and a light detector that detects light emitted from the light source and transmitted through or reflected from the openings. The plurality of openings are arranged periodically in a first direction in the metal film, and both a size of each of the plurality of openings and an interval thereof in the first direction are equal to or less than the wavelength of the light.

    摘要: A DNA fragment distinct from the epidermal growth factor receptor (EGFR) and erbB-2 genes was detected by reduced stringency hybridization of v-erbB to normal genomic human DNA. cDNA cloning revealed a predicted 148 kd transmembrane polypeptide with structural features identifying it as a member of the erbB family, prompting designation of the new gene as erbB-3. It was shown to be expressed as a 6.2 kb transcript in a variety of normal tissues of epithelial origin. Markedly elevated erbB-3 mRNA levels were demonstrated in certain human mammary tumor cell lines. These findings indicate that increased erbB-3 expression, as in the case of EGFR and erbB-2, plays a role in some human malignancies. Using erbB-3 specific antibodies (polyclonal or monoclonal), the erbB-3 protein was identified as a 180 kDa glycoprotein, gp180.sup.erbB-3. The intrinsic catalytic function of gp180.sup.erbB-3 was uncovered by its ability to autophosphorylate in vitro. These findings, combined with the detection of constitutive tyrosine phosphorylation of gp180.sup.erbB-3 in 4 out of 12 human mammary tumor cell lines, implicate the activated erbB-3 product in the pathogenesis of some human malignancies. Thus, this invention also relates to a method for detecting a receptor ligand capable of either activating or down-regulating the receptor protein, as well as procedures for purifying the resultant ligand; and a method of screening potential ligand analogs for their ability to activate the receptor protein.
