Product Name :His-tag (4C2) monoclonal antibody
Application_all :WB:1:5000~10000
IP:1:50~100
IF:1:50~200
Background :The H-H-H-H-H-H motif is used as a tag on many recombinant proteins to facilitate purification. A system that has proven to be very successful relies on the insertion of a six histidine (His6) sequence in the N-terminus of the encoded protein, allowing for efficient coupling to Ni2+-chelating resins and purification by single step affinity chromatography. This polyhistidine sequence can then be removed by specific cleavage at sites recognized by enzymes such as thrombin or enterokinase, permitting the separation of the target protein from the polyhistidine tag.
Product :1mg/ml in PBS with 0.02% sodium azide, 50% glycerol, pH7.2
Purification&Purity :The antibody was affinity-purified from mouse ascites by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE).
Storage&Stability :Store at 4°C short term. Aliquot and store at -20°C long term. Avoid freeze-thaw cycles.
Specificity :His-tag (4C2) mAb detects over-expressed or recombinant proteins containing the 6×His epitope tag.

Figure3 :IF image of AP0032M stained HEK293F cells, transfected with pcDNA3.1-His-TfR-hFC. The cells were 4% paraformaldehyde fixed (15 min) and then incubated in 10% normal goat serum for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody His-tag mAb #AP0032M(1:50) overnight at 4°C. The secondary antibody (Green) was Goat anti-Mouse IgG (H+L) -FITC#BS50950. Hoechst33342 #BD5010 was used to stain the cell nuclei (blue).
