A former boss of mine swore by fish skin gelatine, a liquid of the
colour and consitency of used motor oil, but freely soluble in PBS. The
stuff is available from Sigma, but be carefull: their bottle cap is ill
designed and you won't be able to open it a second time. BSA or common
gelatine are also possible.
