Interleukin 4 (IL4) is a cytokine that induces differentiation of naive helper T cells (Th0 cells) to Th2 cells. It is used for dendritic and T cell therapy. Upon activation by IL-4, Th2 cells subsequently produce additional IL-4 in a positive feedback loop. The cell that initially produces IL-4, thus inducing Th0 differentiation, has not been identified, but recent studies suggest that basophils may be the effector cell. It is closely related and has functions similar to Interleukin 13. Recombinant, GMP rec. E. coli interleukin-4 for cell culture supplied by GENTAUR. Free samples on request.
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.
Plasmid mini made and maxi DNA purification kits can be silica gel or anion exchange, endotoxin free and are used to produce pure plasmids that are small DNA molecules within a cell separated from chromosomal DNA and can replicate independently. They are most commonly found in bacteria as small circular, double-stranded DNA molecules; however, plasmids are sometimes present in archaea and eukaryotic organisms. In nature, plasmids often carry genes that may benefit the survival of the organism, for example antibiotic resistance. While the chromosomes are big and contain all the essential information for living, plasmids usually are very small and contain only additional information. Artificial plasmids are widely used as vectors in molecular cloning, serving to drive the replication of recombinant DNA sequences within host organisms.
