  • 相关性Fluorescein is a fluorophore commonly used to label proteins - protein-fluorescein conjugates are not usually susceptible to precipitation. In addition to its relatively high absorptivity, excellent fluorescence quantum yield and good water solubility, fluorescein has an excitation maximum of 494 nm that closely matches the 488 nm spectral line of the argon-ion laser, making it an important fluorophore for confocal laser-scanning microscopy and flow cytometry applications. Its fluorescence is pH sensitive and is significantly reduced below pH 7. Fluorescein emits most strongly between 500 and 550 nm, but it has a relatively broad emission spectrum reaching to over 600 nm. Several derivatives of fluorescein are commonly used, including FITC (fluorescein isothiocyanate), carboxylates and succinimidyl esters.

Thank you for contacting us.

Without a direct comparison, it is a little difficult to choose between the two. The ab6656 datasheet also has a review of IHC with TSA amplification on frozen tissue, after applying the antibody at a dilution of...

Thank you for your enquiry. The concentration of this antibody is 1.000 mg/ml, however the working dilution/concentration needs to be determined since the signal depends on several factors (such as expression levels of the target, sample preparatio...

Thank you for your phone call today and for your patience while I was in contact with the lab. The lab confirmed that ab6656 has been tested on FITC-conjugated proteins, and so the antibody is appropriate for your studies. I hope this informatio...

Thank you for your enquiry. Yes, I would consider it highly likely that you will be able to use an anti-fluorescein antibody to immunoprecipitate cross linked chromatin associated with your small molecule. You may also wish to consider NChIP as thi...

Thank you for your enquiry. Yes, the chromogen AEC kit is used after using the HRP conjugated fluorescein antibody in immunohistochemical techniques. If you are doing ELISA then a TMB kit is better.

Sorry, we do not have any data on the specific activity of the HRP.
