MaxLight(TM) 490 is a new Blue-Green photostable dye conjugate comparable to DyLight(TM)488, Alexa Fluor(TM)488 and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (491nm), Emission (515nm), Extinction Coefficient 73,000. eIF-2a is a 36kD protein and is ubiquitously expressed in many cell types. The eIF-2 protein, which is composed of three subunits (alpha, beta and gamma), is one of the key molecules in the initiation of translation. The phosphorylation of eIF-2a is an important regulatory process in protein synthesis. In mammalian cells, eIF-2a is phosphorylated at serine 51 by at least two kinases: the heme-controlled repressor (HCR) and the interferon inducible double stranded RNA-dependent protein kinase (PKR). Phosphorylation of eIF-2a blocks the GDP-GTP exchange activity of eIF-2b, resulting in the suppression of protein synthesis. Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1:500-1:1000 Optimal dilutions to be determined by the researcher. Recommended Positive Control: Human Jurkat, CEM and HeLa cells, mouse 3T3L1 and rat PC-12 cells. Storage and Stability: Store product at 4C in the dark. DO NOT FREEZE! Stable at 4C 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(TM)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.
