Sino Biological Inc. have advanced antibody development platform, including Immunohistochemistry / IHC, Flow Cytometry / FACS, Immunofluorescence / IF, Immunofluorescence / IF/ ICC, Immunoprecipitation / IP, Western Blot / WB and ELISA. Sino Biological Inc. has developed nearly 1700 Immunofluorescence / IF / ICC antibodies, this provides an effective tool for scientists. These antibodies include different research areas, including cancer, stem cells, diagnostic and Biomarkers etc.. The antibodies were extensive validation by multiple cell types, including cancer cells, such as Hela, MCF7 and HepG2 etc., and stem cells, such as HESC (human embryonic stem cell) and MSC (mesenchymal stem cells).
Immunofluorescence / IF / ICC is a laboratory technique that uses antibodies to detect specific peptides or protein antigens in the cell via specific epitopes. Immunofluorescence / IF / ICC allows researchers to evaluate whether or not cells express the target antigen. Moreover, Immunofluorescence / IF / ICC allow researchers to know sub-cellular location of target antigen.
Hela cell line is the human cervical carcinoma cell line.Hela cell line is the oldest and most commonly used human cancer cell line which is successfully cloned in 1955. Hela cell line is widely used in biology research and biomedical research field which was found contaminate many other cell lines in laboratory. Hela cell line is often used in Immunofluorescence / IF / ICC test.
Immunofluorescence staining of Human TNFRI in Hela cells. Cells were fixed with 4% PFA, permeabilzed with 0.3% Triton X-100 in PBS, blocked with 10% serum, and incubated with rabbit anti-Human TNFRI monoclonal antibody (15 µg/ml) at 4℃ overnight. Then cells were stained with the Alexa Fluor® 488-conjugated Goat Anti-rabbit IgG secondary antibody (green) and counterstained with DAPI (blue). Positive staining was localized to cytoplasm.
