- Clonality:
- Monoclonal
- Extra Details:
- Numerous protein and ribonucleoprotein components are required to catalyze pre-mRNA splicing. The SR proteins are essential splicing factors. They regulate alternative splicing of many pre-mRNAs. Alternative splicing is a major mechanism for controlling expression of cellular and viral genes. SR proteins are a family of highly conserved serine/arginine rich RNA-binding proteins. Nine human SR proteins including SF2/ASF are currently known. Based on primary sequence and on motifs shared with other proteins, human SF2/ASF is a 248aa protein composed of four domains. SF2/ASF exists predominantly or exclusively in a highly phosphorylated state in a majority of cells. Applications: Suitable for use in Immunofluorescence, Western Blot and Immunoprecipitation. Other applications not tested. Recommended Dilutions: Optimal dilutions to be determined by the researcher. Molecular Weight: Calculated MW: 27.7kD Western Blot: ~33kD (Doublet or triplet bands sometimes evident due to phosphorylation differences). Recommended Control: HeLa cells Storage and Stability: Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: FITC conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Note: Applications are based on unconjugated antibody.
- Host:
- Mouse
- Immunogen:
- Recombinant human SF2/ASF protein.
- Isotype:
- IgG2b
- Physical State:
- Supplied as a liquid in PBS, pH 7.2. No preservatives added. Labeled with Fluorescein isothiocyanate (FITC).
- Purity:
- Purified by Protein A affinity chromatography from ascites.
- Shipping Conditions:

- Specificity:
- Recognizes the N-terminal portion (aa1-97) of human SF2/ASF protein comprising the RNA-recognition motif (RRM1). Reactivity is not affected by phosphorylation state of SF2/ASF. Species Crossreactivity: mouse and rat. Crossreactivity expected with other species because SF2/ASF is highly conserved.
