XIAO-WEN CHENG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Donor plasmid vectors
    Patent number: 11674157
    Abstract: Certain donor plasmid vectors such as pFastBac™1 and pFastBac™ Dual lack a cis DNA element upstream of the polh translation start codon (ATG) present in wild type (wt) Autographa californica multiple nucleopolyhedrovirus (AcMNPV), and contain a SV40 pA fragment. When a cis DNA element is inserted upstream of the 50 bp polh promoter and SV40 pA was replaced with a AcMNPV polh pA signal in pFastBac™1 and pFastBac™Dual, certain protein expression levels in High Five™ cells using the Bac-to-Bac® system reached that of the wt AcMNPV.

  • Recombinant baculovirus expression vector and cell
    Patent number: 9909106
    Abstract: A recombinant baculovirus expression vector or cell comprising an engineered baculovirus fp25k gene with one to three modified or mutated spots, the modified spots comprise the two 7-adenine mononucleotide repeats (MNR) and the 10th TTAA site. The invention also provides the method of making the vector and baculovirus.

  • Pacemaker signal detecting method, pacemaker signal detecting system and electrocardial detecting device
    Patent number: 9687657
    Abstract: The present invention provides a pacemaker signal detecting method, a pacemaker signal detecting system, and an electrocardial detecting device. The pacemaker signal detecting system pre-processes an original pacemaker signal separated from a pacemaker electrocardial signal, calculates a number of basic morphological features based on the pre-processed original pacemaker signal, confirms an authenticity of a pacemaker signal according to the calculated basic morphological features, and records positions of the true pacemaker signal has been confirmed. The basic morphological features include a width, a slew rate, and amplitude of the pacemaker signal. The electrocardial detecting device of the present invention can detect the pacemaker signal more precisely and output the electrocardial signal marked with the pacemaker signal.
