... change. The muscle contracts simple if it's switched on. ACh (small 'h' so not to get confused with adrenocorticohormone!) slows down the RATE of APs - so how many times it's switched on in a given period of time. Otherwise all correct, and just the reverse for epinephrine. 1. Stroke volume in ...

... of action potentials that are fired, thus slowing the overall speed of contractions. Likewise norepinephrine/noradrenaline speed up the firing of APs and so speed heart beating. The last bit's just telling you that norepinephrine can also be produced in places other than the nerve terminals in ...

... A combination of polyacrylamide, deionized water (ddH20), Tris Buffer (to maintain pH), Ammonium Persulfate (APS), SDS, and TEMED are mixed together to create a polyacrylamide gel that can be thought as a matrix net like structure. The resolving gel is where ...

hi you may try the following - check again concentrations of acrylamide stock, TEMED and APS you use to prepare your gels - 4.5 h is typical for 16% protein gels (5 cm run), are you sure everything is ok with your 'ingredients'? - use freshly prepared gels, do not store ...
