  • 特記事項(精製)
    This product was prepared from monospecific antiserum by immunoaffinity chromatography using Rabbit IgG coupled to agarose beads followed by solid phase adsorption(s) to remove any unwanted reactivities and extensive dialysis against the buffer stated above. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Goat Serum, Rabbit IgG and Rabbit Serum.

レビューと Q&A

We have used this secondary antibody for immunocytochemistry with 2,2'-thiodiethanol (TDE) mounting media. TDE quenches the fluorescence of conventional green fluorophores (e.g., Alexafluor 488, GFP, etc....), but the original description of this mounting media (PMID: 17131355) reported an increase in the relative quantum yield of Cy3. We tried this Cy2-conjugated secondary antibody following TDE mounting of stained HEK293 cells and saw excellent signal from the green channel. We did not observe bleaching of the signal following Z-stack image acquisition.

The protocol for obtaining the image shown in the figure was a standard ICC protocol, followed by the TDE mounting procedure from the original TDE paper (PMID: 17131355), using sequential immersions in increasing concentrations of TDE. Slides were imaged on a Zeiss Observer Z1 with LED-based excitation (488 nm). Acquired images were deconvolved and the included image is a maximum intensity projection.

Thank you for contacting us.

Yes, either ab6940 or ab97075 will work as a suitable secondary with ab7779. "Pre-adsorbed" means that we pre-treated the secondary antibody with normal sera from certain species to remove cross-reactiv...
