- 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. 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 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.
