RESUMEN
Objective:To produce the mcAb specifically reacting with lung cancer and to purificate its antigen.Methods:The mice were immunized with A549, the mcAb 2B9 was screened by indirect cell ELISA and immunohistochemistry, and its antigen was purificated by immunoaffinity chromatography.Results:A mcAb was obtained, which could react to lung cancer but very little or not to normal lung tissue and other caner tissues, and the antigen of the mcAb was purificated from the cell lysate.Conclusion:A mcAb which can react to lung cancer have been obtained and its antigen was purificated, they may be useful on clinic for diagnosis and prognosis of lung cancer.
RESUMEN
Objective:To produce the mAb which specifically reacting with colorectal cancer confirmed by the tissue microarray technology.Methods:The mice were immunize with LOVO, and the mAb were screened by indirect cell ELISA and immunohistochemistry.Results:A McAb was obtained which can react to the colon cancer, but very little or not to normal tissue and other caner tissues.Conclusion:A McAb which can react to the colon cancer have been obtained,and the McAb can be useful on clinic for diagnosis and prognosis of colorectal cancer.
RESUMEN
Objective:To establish a protein biochip flat to identify the subtype of interfon by adopting the 6 mAb which we have prepared.Methods: Recombinant human interferon was onto the NHS modified gold biochips.then the protein biochips were incubated with the 6 mAb.Cy3 conjugated sheep anti-mouse IgG was used to detect the antigen-antibody.Arrays are imaged using a fluorescence scanner (GenePix4100A) at 532 nm for Cy3.This method was compared with the traditional ones:ELISA,Western blot.Results:The results showed that this flat had speciality to identify the subtype of interfon. Conclusion: The protein biochip plat can provide a practical method to identify the subtype of interfon.It also has some advantages:high quantities;simple operation;low sample dosage and high repetition.
