Abstract: A novel human epidermal growth factor receptor-like protein has been identified, designated TEGFR. Provided herein is the nucleic acid sequence and deduced amino acid sequence of this protein. The invention relates to the measurement of its protein by immunological means or the measurement of its mRNA by recombinant DNA means in human biological samples. The invention also pertains to the use of its cDNA to produce a recombinant source of the protein. Moreover, the invention relates to its therapeutic use to inhibit the activity of epidermal growth factor receptor. Lastly, the invention also concerns the diagnostic and therapeutic use of this protein for human cancers.

Abstract: A simple and rapid method by which lipids can be measured quantitatively or qualitatively. The method involves the use of a labelled lipid of which one is interested in measuring or a different lipid reacting similarly to the lipid of interest. The labelled lipid is added to an unknown specimen and to a set of standard(s) containing various amounts of the lipid of interest. The label is allowed to interact. A portion of the label is then selectively removed of which the degree of the removal of the label is dependent upon the amount of the lipid initially present. The amount of lipid originally present in the unknown specimen can therefore be ascertained by extrapolating the amount of label present in the unknown specimen to the amount present in the identically treated standard(s).
