I can confirm that ab37361 is not tested to be endotoxin free and therefore is most probably not suitable for your application.

But I am happy to point you to ab37371 (Rat IgG (low endotoxin, azide free) - Isotype Control) which is tested to be low endotoxin (Endotoxin level of <25EU/mL) and azide free:

https://www.abcam.com/index.html?datasheet=37371 (or use the following: https://www.abcam.com/index.html?datasheet=37371).

ab37371 is not tested for in vivo applications and therefore is not covered by our guarantee.

Thank you for your inquiry.

I am sorry to confirm that ab37361 is not aa IgG2b antibody but a mixture of rat IgGs of all isotypes.

I can suggest to following antibody for your customer's experiments:

It is of the IgG2b isotype and is supplied in PBS. Please review the datasheet for more information:
