Abstract:
Disclosed herein is an expression system and uses thereof. The expression system comprises two vectors that express two fusion proteins and a glutaminyl cyclase (QC) with E45Q mutation, so as to autonomously produce a target protein having a N-terminal pyroglutamate (pGlu) residue in a host cell. The first fusion protein is composed of a maltose binding protein (MBP) and a tobacco etch virus protease (TEVP); and the second fusion protein includes in sequence, a thioredoxin, a S-tag, a linker having a TEVP recognition site therein, a target protein, and a (His)-6-tag. The second fusion protein is cleaved by the TEVP that is expressed by the first fusion protein, and then catalyzed by QC with E45Q mutation so as to autonomously produce the target protein having a N-terminal pGlu residue in the host cell.
Abstract:
Described herein are synthetic glycan conjugates, immmunogenic compositions thereof, vaccines thereof, and kits thereof. The present invention further provides methods of using the synthetic glycan conjugates, immunogenic compositions, or vaccines thereof to treat and/or prevent and/or diagnose proliferative diseases such as cancer. The provided glycan conjugate comprises a carrier and a glycan moiety of Formula (I-i) or Formula (I-ii): (structurally represented).
Abstract:
An ion trap mass spectrometer and methods for obtaining a mass spectrum of ions by scanning an RF frequency applied to the linear ion trap for mass selective ejection of the ions by using two power amplifiers to apply opposite phases of the RF to x and y electrodes.
Abstract:
The preset invention relates to a promoter to target a fluorescent protein to the muscles of fish, such as A. nigrofasciatus, for ornamental purposes, which is a Mlc3 (myosin, light polypeptide 3, skeletal muscle) promoter. The Mlc3 promoter has the nucleotides of tilapia (Oreochromis niloticus) myosin light chain 3 (Mlc3) promoter region, which is potential to be a tilapia Mlc3 promoter to enhance protein expression in muscle of fish, particularly for the generation of ornamental fish.
Abstract:
The preset invention relates to a new method for wound healing, particularly in burns, comprising Epinecidin-1 (Epi-1) or Pardaxin (GE33), optionally in the incorporation into collagen.
Abstract:
The present invention relates to a mutant cyanobacterium and a method to increase photosynthetic growth and/or biomass production of cyanobacteria by using the same.
Abstract:
Methods of using fibrillar proteins are provided for suppressing cancer metastasis. Cancer metastasis is the most common cause of treatment failure and death in cancer patients. Tumor cell invasion and/or migration can be significantly inhibited after fibrillar proteins (rVP1, F-HSA, and F-BSA) treatment in vitro. In addition, rVP1 can significantly suppress murine and human breast cancer metastasis and human prostate and ovarian cancer metastasis in vivo while F-HSA can significantly suppress murine breast cancer metastasis.
Abstract:
The present invention discloses a novel isolated antibody that specifically binds to an N-phenyl-acetamide group. Also disclosed are related compositions, kits, methods for detecting protein S-nitrosylation or oxidation vivo or in vitro, and drug screening methods.
Abstract:
A pharmaceutical composition for use in killing and/or inhibiting the growth and/or proliferation of a microorganism in a subject in need thereof, or for treating a subject afflicted with a microbial infection is disclosed. The composition comprises: (a) an effective amount of an isolated peptide, wherein the peptide comprises the arginine-rich carboxy-terminal region of hepatitis B virus core protein (HBc) and exhibits an antimicrobial activity; and (b) a pharmaceutically acceptable carrier. The peptide exhibits an activity against Gram-negative bacteria, Gram-positive bacteria, and/or fungi.
