A requirement for a buffer solution is that it should possess a weak … WebThe HCl/KCl system is not a buffer because the $\ce{Cl-}$ anion is the conjugate base of a strong acid, and therefore remains deprotonated; the $\ce{Cl-}$ anion does not contribute to the overall $\ce{pH}$. Since $\ce{HCl}$ is the only source of protons, and there is no other species to take up the protons, the HCl/KCl system is not a buffer. ...

WebTris-HCl tends to reduce binding and should only be used when metal-protein affinity is fairly high. High concentrations of salt or detergents in the buffer normally have no effect on the adsorption of protein and it is good practice to maintain a high ionic strength (e.g., 500 mM to 1 M NaCl) to avoid unwanted ion exchange effects.
