Weitere Details:: Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of enzymes involved in arginine catabolism. The open complex (sigma-54 and core RNA polymerase) serves as the receptor for the receipt of the melting signal from the remotely bound activator protein glnG(ntrC). Applications: Suitable for use in ELISA, Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 0.5ug/ml Optimal dilutions to be determined by the researcher. Hybridoma: Sp2/0 myeloma cells with spleen cells from Balb/c mice. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C.
