SpecificityThe specificity of this antibody has been confirmed by WB and IHC against the antigen. Human; mouse; rat; rabbit;
Species ReactivityHuman, Mouse, Rabbit, Rat
Immunogen DescriptionA synthetic peptide (QTTDNLLPMSPEEFDE) corresponding to a region (718-733) from the C-terminus of human STAT1 isoform alpha/p91. To enhance the immunological response, this peptide was coupled to carrier protein BSA.
ConjugateUnconjugated
Purity DescriptionAffinity purified on antigen column
Application DetailsImmunohistochemistry (IHC) and Western Blotting (WB). A concentration of 1.0-2.0 µg/mL is recommended for WB. Human STAT1 (isoform alpha/p91) has a predicted length of 750 residues and MW of 87 kDa. A concentration of 1.0-2.0 µg/mL is recommended to detect the protein in formalin fixed and paraffin embedded tissues. Antigen retrieval is required. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

FormatLyophilized from a solution containing 5mg BSA, 0.9mg NaCl, 0.2mg Na2HPO4, 0.05mg Thimerosal, 0.05mg NaN3.
Reconstitution InstructionsSpin vial briefly before opening. Reconstitute with 100 µL sterile-filtered, ultrapure water to achieve a 1 mg/mL concentration. Centrifuge to remove any insoluble material.
Storage InstructionsAfter reconstitution of lyophilized antibody, aliquot and store at -20°C for a higher stability (up to 6 months). Avoid freeze-thaw cycles. Reconstituted antibody can be stored for 1 month at 2-8°C. Unopened, lyophilized vial may be stored for 12 months from date of receipt at -20°C.

Scientific BackgroundSTAT1 belongs to the STAT (signal transducers and activators of transcription) family of proteins. STAT proteins undergo tyrosine/serine phosphorylation in response to cytokines and growth factors. As a result of this phosphorylation, STAT proteins form dimers and are translocated to the nucleus where they act as transcription factors. Alternative splicing of the STAT1 gene gives rise to the STAT1 alpha and beta isoforms.
