Question 1

Friday 03-August-2007

The product desription describes this as being Cy5 antibody. The conjugation notes describe this as being Cy5.2 conjugated. Could you please confirm the label and structure of the fluorophore?

ANSWER:

 

Thank you for your enquiry.

I believe Cy5.29 OSu is the same as Cy5, but refers more specifically to the cyanine derivative, a succinimide ester, that is used for conjugation. The following paper describes this ester:

Cytometry. 1990;11(3):418-30. PMID: 2340776

I hope this information helps. Please do not hesitate to contact us if you need any more advice or information.

Question 2

Monday 17-June-2002

I would like to use this donkey anti-goat secondary for a dual staining flow cytomytry experiment. The other secondary is goat anti-mouse IgG so I was wondering if the donkey anti-goat would recognize the other secondary or would the fluorphore's linked to the goat anti-mouse secondary mask any potential epitopes. Thanks

ANSWER:

 

This antibody will indeed recognise the other secondary. You need to use a secondary antibody to the mouse IgG raised in a species other than goat, preferably donkey (if you want to use ab6566). Look for a donkey anti-mouse IgG fluorphore conjugated secondary antibody on the Abcam website.
