Abstract: The present invention relates to a novel process for removing sidewall residue after dry-etching process. Conventionally, after dry-etching, photoresist and sidewall residues are removed by ozone ashing and hot sulfuric acid. Normally, they are hard to be removed completely. It was found in the present invention that the addition of fluorine-containing compound, preferably hydrogen fluoride and ammonium fluoride, in sulfuric acid results in complete removal of photoresist and sidewall residue without the need for stripper. The process is simple and does not affect the original procedures or the other films on the substrate. The present invention also relates to a novel solution for removing sidewall residue after dry-etching, which comprises sulfuric acid and a fluorine-containing compound, preferably hydrogen fluoride and ammonium fluoride, in the range of from 10:1 to 1000:1 by weight.

Abstract: The present invention provides mice that have had their PTP-1B genes disrupted by targeted homologous recombination. The mice have no detectable PTP-1B protein, yet appear to be physiologically normal. However, in the fed state on a normal diet, the mice have half the level of circulating insulin as their wild-type littermates. In glucose and insulin tolerance tests, the mice show an increased insulin sensitivity. When fed a high fat, high carbohydrate diet, the mice show a resistance to weight gain as compared to their wild-type littermates. Methods making the mice and cell lines derived from the mice are also provided. The present invention also provides methods of identifying inhibitors of the enzymatic activity of PTP-1B as well as inhibitors identified by such methods.

Abstract: A process for purifying papillomavirus virus-like particles (VLPs) includes the step of passing a partially purified VLP-containing solution through a hydroxyapatite chromatography column. The VLPs are then eluted using a buffer containing phosphate anion. The advantages of this method include the recovery of a high yield of intact VLPs.
