Goat Anti-Rat IgG H&L (HRP) preadsorbed (ab7097)

Thank you for contacting us.

Please reffer the customer to our FAQs and our Storage guide:

"For many of our antibodies, freezing at -20oC or -80oC in small aliquots is the optimal storage condition. Aliquotting minimizes damage due to freezing and thawing, as well as contamination introduced by pipetting from a single vial multiple times. Aliquots are to be frozen and thawed once, with any remainder kept at 4oC. Upon receiving the antibody, centrifuge at 10,000 x g for 20 seconds to pull down solution that is trapped in the threads of the vial, and transfer aliquots into low-protein-binding microcentrifuge tubes. The size of the aliquots will depend on how much one typically uses in an experiment. Aliquots should be no smaller than 10 µl; the smaller the aliquot, the more the stock concentration is affected by evaporation and adsorption of the antibody onto the surface of the storage vial.


Enzyme-conjugated antibodies, should not be frozen at all and should instead be kept at 4oC. Freezing and thawing will reduce enzymatic activity in addition to affecting the antibody binding capacity.

However, when the HRP conjugated abs wasn't thought in between, the perfomance should still be ok.

The rule of the thump is that a -80C stored antibody should be fine for the next 10 years.


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

As requested, I have issued a free of charge replacement for ab7097, anti-rat IgG cross-absorbed to remove reactivity with mouse IgG. I apologize for the misunderstanding on our part and wish you the best of luck with your research.
