- Extra Details:
- MaxLight™ 490 is a new Blue-Green photostable dye conjugate comparable to DyLight™488, Alexa Fluor™488 and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (491nm); Emission (515nm); Extinction Coefficient 73,000. 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 in the dark. DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight™490 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Note: Applications are based on unconjugated antibody.
