Opis

General description

55 kDa

c-fos is a member of a family of immediate early gene (IEG) transcription factors (other members include Jun and Egr-1) also identified as proto-oncogenes. The basal expression of c-fos and other IEGs is typically low but increases relatively quickly and often dramatically (15-30 min for mRNA; 30-60 min for protein) in response to changes in cellular activity typically caused by external stimuli, such as stress or neuronal activation. Thus, these IEGs are being used to indicate specific activity driven cellular activation including the identification of neurons activated by various growth factors, neuroactive drugs, and correlated changes in behavioral or physiological states.

Immunogen

Synthetic c-fos peptide (residues Ser.Gly.Phe.Asn.Ala.Asp.Tyr.Glu.Ala. Ser.Ser.Ser.Arg.Cys) corresponding to amino acids 4-17 of human Fos, conjugated to bovine thyroglobulin.

Application

Immunohistochemistry: 1:500-1:4000, 2-8°C 1-3 days. Stains both fresh frozen and paraffin embedded tissue samples by indirect immunofluorescence and immunoperoxidase.

Recommended fixation is 4% PFA with 0.5% picric acid {Li et al 1999}; triton X-100 pretreatment in the block only; antigen retrieval for paraffin sections is recommended. Microwave citric acid treatment suggested.

Western blot: 10 μg/mL. Detects a band at approximately 55 kDa.

Optimal working dilutions must be determined by the end user.

Physical form

Ammonium Sulfate Precipitation

Format: Purified

Purified immunoglobulin. Lyophilized, no preservatives. Reconstitute with 500 μL of sterile distilled water (1 mg/mL).

Preparation Note

Maintain lyophilized material at -20 to -70°C for up to 12 months. After reconstitution maintain at -20°C in undiluted aliquots for up to one year.

Avoid repeated freeze/thaw cycles.

During shipment, small volumes of product will occasionally become entrapped in the seal of the product vial. For products with volumes of 200μL or less, we recommend gently tapping the vial on a hard surface or briefly centrifuging the vial in a tabletop centrifuge to dislodge any liquid in the container′s cap.
