anti-Flag-Tag Monoclonal Antibody

DYKDDDDK

FLAG, DYKDDDDK

DYKDDDDK-Tag (Flag-Tag) antibody detects over-expressed proteins containing the D epitope tag fused to either the amino- or carboxy-terminus of targeted proteins. Epitope tags are usually for the labeling and detection of proteins using immunoblotting, immunoprecipitation and immunostaining techniques. Due to their small size, they are unlikely to affect the tagged protein’s biochemical properties. The DYKDDDK epitope tag is widely used to detect expression of recombinant proteins in bacteria, yeast, insect and mammalian systems.

The antibody solution should be gently mixed before use.

This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.

If you buy Antibodies supplied by Biovision they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.An anti-flag tag (FLAG fusion protein) is use to detect a FLAG-tag, or FLAG octapeptide, or FLAG epitope that is a polypeptide protein tag that can be added to a protein using recombinant DNA. This FLAG-tags have the sequence DYKDDDDK motiv.  These tags are very useful to do protein purification by affinity chromatography. Also separation of recombinant, overexpressed proteins from cell lysates is done by FLAG go HIS tags. FLAGS are also used in the isolation of protein complexes with multiple subunits, because its mild purification procedure tends not to disrupt such complexes. It has been used to enrich proteins of height purity and quality to see the 3D crystal structure with x-ray. Suitable for in vivo use in cells. For electrophorese protein detection rabbit polyclonals anti Flag conjugation are the most suited antibodies.

Monoclonals of this antigen are available in different clones. Each murine monoclonal anibody has his own affinity specific for the clone. Mouse monoclonal antibodies are purified protein A or G and can be conjugated to FITC for flow cytometry or FACS and can be of different isotypes.
