摘要:
In a process of forming a hydrogel from a mixture comprising hydrogen peroxide (H2O2), horseradish peroxidase (HRP), and a polymer comprising a crosslinkable phenol group, the gelation rate in the solution and the crosslinking density in the hydrogel can be independently adjusted or controlled by selection of the molarity of H2O2 and concentration of HRP in the solution when the molarity of H2O2 is limited to be within a range and the concentration of HRP is limited to be above a threshold. A method for determining the range and threshold is disclosed. The hydrogel may be used to grow cells, in which case, the molarity of H2O2 may be selected to affect the differentiation or growth rate of the cells in the hydrogel. Also, the hydrogel system may be used for sustained delivery of a therapeutic protein, for example in the treatment of liver cancer, fibrosis or hepatitis.

摘要:
Provided herein are a hybridoma cell line producing monoclonal antibody against foot-and-mouth disease virus (FMDV), the monoclonal antibody therefrom, reagent and kit for ELISA, and immunoassay method. The hybridoma cell line CmA40 as deposited under American Type Culture Collection patent deposit number PTA-11304 is produced by cell fusion of a parental cell and a myeloma cell line. The parental cell is a splenocyte isolated from the spleen of a mouse immunized by an antigen derived from a 3ABC non-structural protein (NSP) of FMDV. The antigen used here is expressed by a prokaryotic cell. The monoclonal antibody produced by the hybridoma cell line CmA40 as deposited under American Type Culture Collection patent deposit number PTA-11304 can specifically recognize a 3ABC polypeptide and does not cross-react with an antiserum of swine vesicular disease virus.
