Mouse MRA and Aorta is 2 for rat try 5

Karima Ait-Aissa

Isn't it too low for the mouse aorta?

Hermes Vieira Barbeiro

I work with isolated aorta more than 20 years and use as initial tension

1,5g for the rat

1,0g for the mouse

2,0g for the rabbit

OK thanks. Do you have any idea for the rat carotide and mesenteric artery?

No I haven´t . Sorry.

David C. Ellinsworth

I Have seen people use up to 15mN for mouse aorta which I thought was ridiculously high. Theoretically it should be lower in smaller blood vessels because of course MAP is lower. I think for mesenteric you should use 5mN.
