Produktbeschreibung

Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor controls the expression of flagella-related genes. Source: Recombinant protein corresponding to aa1-239 from Escherichia coli RNA polymerase sigma factor for flagellar operon, fused to 6X His-Tag at N-terminal, expressed in E.coli.
