摘要:
The gas or gas-carried suspended matter indicator tube includes a reagent therein for detecting gases or suspended matter in the gas which are passed through the tube. The tube is drawn down at each end and sealed. Each end of the tube or the portion of the tube at which the reagent ends, is retained by fixing elements, which comprise glass granules which are sintered.
摘要:
The present invention provides a new approach to creating novel polynucleotide sequences by point mutation and recombination in vitro of a set of parental sequences. The new polynucleotide sequences can be useful in themselves or they can be used for the templated synthesis of polymers, e.g. polypeptides composed of α-amino acids as occurring naturally in protein synthesis or polymers comprised of β-amino acids or other building blocks as described (Templated molecules).
