| 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. The expression of topoisomerase II alpha is strongly restricted to proliferating cells. The topoisomerase II alpha antigen is preferentially expressed during G1, S, G2 and M phase of the cell cycle, while resting, non-cycling cells (G0 phase) lack topoisomerase II alpha. In addition, constantly proliferating cells (e.g. cell lines) react positively to topoisomerase II alpha during the entire cell-cycle. This specificity for proliferating cells might make it a useful tool for determination of the proliferative fraction in solid tumors such as mammary carcinomas and gangliomas. Applications: Suitable for use in Immunohistochemistry, Western Blot, Immunoprecipitation, Immunocytochemistry and Flow Cytometry. Other applications not tested. Recommended Dilutions: Western Blot: 1-10ug/ml Immunohistochemistry: 5-10ug/ml. Strong nuclear staining only in proliferating cells. The epitope recognized by the antibody is also detectable in paraffin-embedded tissue sections. Immunocytochemistry: 5-10ug/ml Optimal dilutions to be determined by the researcher. 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. |
