- 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: Western Blot: 2ug/ml 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: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
- Host:
- Mouse
- Immunogen:
- Recombinant human SF2/ASF protein.
- Isotype:
- IgG2b
- Physical State:
- Supplied as a liquid in PBS, pH 7.4, 0.09% sodium azide.
- Purity:
- Purified by Protein A affinity chromatography from ascites.
- Shipping Conditions:
- Blue Ice
- 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.
