摘要:
The present invention relates to a method for etching glass or metal using a negative photoresist and a method for fabricating a cliche using the same. In the method for etching glass or metal according to the present invention, since adhesion strength between the negative photoresist and the metal or the metal oxide is excellent, the photoresist layer is not corroded by the metal or metal oxide etching solution, it is unnecessary to produce an inverse photomask, the fabrication process is simple, and a low resolution light source such as mixed wavelength type light source is capable of being used, thus, economic efficiency is ensured.

摘要:
This invention provides an improver for adhesion of a photosensitive resin composition consisting of an N-phenyl-2H-benzotriazole compound represented by the general formula (1) below. This improver is added for example to a photosensitive resin composition containing an alkali-soluble resin and a photosensitizer: wherein R1 to R4 each independently represent a hydrogen atom, a halogen atom or a C1-5 alkyl group; R5 to R9 each independently represent a hydrogen atom, a hydroxyl group, a C1-10 alkyl group, an aryl group, a C7-12 aralkyl group, —R10COOR11, or —R10CO—(OCH2CH2)n-OH provided that at least one of R5 and R9 is a hydroxyl group; R10 represents a C2-5 alkylene group; R11 represents a C1-8 alkyl group; and n is an integer of 2 to 20.

摘要:
Methods for determining a degree of pluripotency in a first putative stem cell relative to a second putative stem cell are provided. In some embodiments the methods include comparing the imprinting status in the first versus the second putative stem cell of a locus selected from among Igf2-H19, Rasgrf1, lgf2R, Kcnq1, and Peg1/Mest. Also provided are methods for distinguishing very small embryonic like (VSEL) stem cells from hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs), methods for isolating VSELs from sources expected to include VSELs, methods for assessing the purity of a very small embryonic like stem cell (VSEL) preparation, and kits that include oligonucleotide primers that can be employed in the practice of the claimed methods.
