  • RelevanceCortisol is the most potent glucocorticoid produced by the human adrenal. It is synthesized from cholesterol and its production is stimulated by pituitary adrenocorticotropic hormone (ACTH) which is regulated by corticotropin releasing factor (CRF). ACTH and CRF secretions are inhibited by high cortisol levels in a negative feedback loop. In plasma a majority of cortisol is bound with high affinity to corticosteroid binding globulin (CBG or transcotin). Cortisol acts through specific intracellular receptors and affects numerous physiologic systems including immune function, glucose counter regulation, vascular tone, and bone metabolism.

To our knowledge, ab1949 nor ab6066 have not yet been tested in detecting canine cortisol and testosterone. However, as cortisol and testosterone are steroids, antibodies raised against them should detect them regardless of the species that they are pr...

Thank you for contacting us and your interest in our products.

We have two antibodies directed against cortisol which have been used in ELISA previously. These are the mouse monolonals ab1949 and ab116600. However these have not been used in a...

Thank you for confirming that information.

The antibodies you have suggested for DHEA (ab54202, ab35062 and ab123987) should be fine for what the customer has requested.

The same is true of the anti-DHEA-S (ab31668). The anti-Cortis...

Thank you for contacting us.

To be honest we do not have an antibody that we have tested with this kind of novel assay, and therefore do not know if it would work nor can we guarantee it.

Although ab1949 may work, I may recommend ab...

Thanks for your inquiry. Yes ab1949 should work in mouse serum. However, there will likely be an issue with non-specific binding of your secondary antibody, which will be an anti-mouse IgG, with the IgG in the mouse serum. Of course, this is assu...
