Biological Activity：Data Not Available.
Physical Appearance：Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation：Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.
Endotoxin：Less than 0.1 EU/μg of rFliAH as determined by LAL method.
Reconstitution：We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.
Stability & Storage：Use a manual defrost freezer and avoid repeated freeze-thaw cycles. - 12 months from date of receipt, -20 to -70 °C as supplied. - 1 month, 2 to 8 °C under sterile conditions after reconstitution. - 3 months, -20 to -70 °C under sterile conditions after reconstitution.
Background：Flagellin protein FliA(H), also named RNA polymerase sigma factor for flagellar operon, Sigma F and Sigma-28, is belonging to the sigma-70 factor family or FliA subfamily. 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. May regulate the expression of genes involved
