MaxLight™550 is a new Yellow-Green photostable dye conjugate comparable to Alexa Fluor™546, 555, DyLight™549 , Cy3™, TRITC and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (550nm); Emission (575nm); Extinction Coefficient 150,000.
DNA damage binding protein (DDB) is a heterodimer that functions in DNA repair, and is associated with the DNA repair deficiency disease xeroderma pigmentosum (XP). The damaged DNA binding function of DDB requires both DDB1 (p125, 127kD) and DDB2 (p48, 48kD) subunits. When the subunits of DDB are expressed individually, p48 localized in the nucleus and p125 localized in the cytoplasm. Co-expression of p125 with p48 resulted in an increased accumulation of p125 in the nucleus, indicating that p48 plays a critical role in the nuclear localization of p125.
Applications
Suitable for use in FLISA, Western Blot and Immunohistochemistry. Other applications not tested.
Recommended Dilution
Sandwich FLISA (Recombinant protein): The detection limit is ~0.3ng/ml as a capture antibody. Immunohistochemistry (Formalin fixed paraffin embedded): 3ug/ml stains DDB1 on human adrenal gland. Optimal dilutions to be determined by the researcher.
