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.
HEK 293 cells are known as human embryonic kidney cells. HEK 293 cells were developed from human embryonic kidney cells. HEK 293 cells are used widely in biology research because HEK 293 cells are very easy to been cultured and transfected. Almost every one of who have cultured cells knows HEK 293 cells. HEK 293 cell line is often used in Immunofluorescence / IF / ICC test.
Immunofluorescence staining of Human SPARCL1 in A431 cells. Cells were fixed with 4% PFA, permeabilzed with 1% Triton X-100 in PBS, blocked with 10% serum, and incubated with rabbit anti-Human SPARCL1 monoclonal antibody (15 µg/ml). Then cells were stained with the Alexa Fluor® 594-conjugated Goat Anti-rabbit IgG secondary antibody, countstained with DAPI (blue). Positive staining was localized to cytoplasm.
Immunofluorescence staining of flag-Tag in 293 cells, transfected with PCMV-CDH1-flag (Figure A), pSTEP2-Flag-FABP4-GST (Figure B), pSTEP2-Flag-ARG1-GST (Figure C), Flag-PRMT5-His (Figure D),Flag-PRMT6-His (Figure E) and His-flag-CD38(Figure F). Cells were fixed with 4% PFA, permeabilzed with 0.3% Triton X-100 in PBS, blocked with 10% serum, and incubated with Mouse anti-flag-Tag monoclonal antibody at 37℃ 1 hour. Then cells were stained with the Alexa Fluor® 488-conjugated Goat Anti-mouse IgG secondary antibody (green) and counterstained with DAPI (blue).
