The present invention relates to artificially synthesized modified mono-methylated lysines and modified mono-methylated lysine derivatized polypeptides. The present invention also relates to production of a completely new antibody by using this modified mono-methylated lysine and modified mono-methylated lysine derivatized polypeptide as an antigen, this antibody can be used in recognizing and enriching the modified polypeptide after the lysine mono-methylated polypeptide being derivatized in vitro. By using this antibody, it is capable of detecting whether a mono-methylation modification is present in amino acids on the polypeptide sequence, the present invention also relates to a preparation method of said antibody. Moreover, the present invention also relates to a method for identifying and quantifying the lysine mono-methylated modified substrate in cell or tissue; more specifically, it belongs to identifying and quantifying the lysine mono-methylated modified substrate in cell or tissue by using proteomics approach of affinity enrichment for specific antibody and mass spectrometry.

The present disclosure relates to a conductive hydrogel including a mussel adhesive protein, a liquid metal, and hyaluronic acid and a preparation method thereof.

Disclosed are immunogenic proteins from Pseudomonas aeruginosa as well as nucleic acids, vectors and transformed cells useful for expression of the proteins. Also disclosed are methods for prophylaxis of infection with Pseudomonas aeruginosa using the proteins, nucleic acids, vectors or transformed cell.

The invention belongs to the field of biochemistry and molecular biology. The present invention provides a mutant of -conotoxin peptide TxID, a pharmaceutical composition and use thereof. The TxID mutant is capable of specifically blocking acetylcholine receptors (nAChRs), in particular, 34, or 6/34 subtype, and has application prospects in the manufacture of a medicament for smoking cessation and detoxification and analgesia, a medicament for treating psychiatric diseases and cancers, regulating appetite, and a tool medicine for neuroscience.

A scorpion venom heat-resistant synthetic peptide (SVHRSP) contains an amino acid sequence of SEQ ID NO 1. One or more amino acids the amino acid sequence can be substituted or deleted. A pharmaceutical composition that contains the SVHRSP has numerous applications. The pharmaceutical composition can be used to protect neuronal cell against amyloid beta-induced toxic effects, or to inhibit the sodium channel current of a hippocampal neuronal cell, or to protect a neuronal cell against NMDA-induced injury. It may also promotes the formation of a pluripotent neural stem cell from a type II astrocyte, or treats a subject, such as a human, having epilepsy, Alzheimer's disease, or Parkinson's disease.

A method for treating wrinkle or aging on a skin of a subject includes applying to the skin a composition that includes a green fluorescent protein-human epidermal growth factor fusion protein as an effective component. Since the fusion protein has an excellent anti-oxidation activity and a high skin cell proliferation effect, it can be advantageously used as a raw material of functional cosmetics having excellent skin regeneration effect like improvement of skin wrinkles and skin whitening.

A liposomal vaccine composition comprises a -amyloid (A)-derived peptide antigen displayed on the surface of the liposome. The vaccine composition also comprises a peptide comprising a universal T-cell epitope encapsulated within the liposome. The vaccine composition also comprises an adjuvant, which may form part of the liposome and may be displayed at least in part on the surface of the liposome. These vaccine compositions are used for treating, preventing, inducing a protective immune response against or alleviating the symptoms associated with an amyloid-beta associated disease or condition or a condition characterised by, or associated with, loss of cognitive memory capacity in a subject. The vaccine compositions may be provided as a kit. Related methods of producing a liposomal vaccine composition are also provided.

The present disclosure is directed to the TNF-related apoptosis inducing ligand (TRAIL) fusions with positively charged proteins, neutrophils engineered to express and secrete such fusions in the context of neutrophil extracellular traps, and methods of use thereof in the treatment of cancer.

A non-integrating viral delivery system is disclosed. The system includes a viral carrier, wherein the viral carrier contains a defective integrase gene; a heterologous viral episomal origin of replication; a sequence encoding at least one initiator protein specific for the heterologous viral episomal origin of replication, wherein expression of the sequence encoding the at least one initiator protein specific for the heterologous viral episomal origin of DNA replication is inducible; and at least one gene, gene product, shRNA, siRNA, miRNA, or other RNA of interest.

The present invention is directed to a method of producing analgesia in a mammalian subject. The method includes administering to the subject an omega conopeptide, preferably ziconotide, in combination with an analgesic selected from the group consisting of morphine, bupivacaine, clonidine, hydromorphone, baclofen, fentanyl l, buprenorphine, and sufentanil, or its pharmaceutically acceptable salts thereof, wherein the -conopeptide retains its potency and is physically and chemically compatible with the analgesic compound. A preferred route of administration is intrathecal administration, particularly continuous intrathecal infusion. The present invention is also directed to a pharmaceutical formulation comprising an omega conopeptide, preferably ziconotide, an antioxidant, in combination with an analgesic selected from the group consisting of morphine, bupivacaine, clonidine, hydromorphone, baclofen, fentanyl, buprenorphine, and sufentanil.
