Webrequired to use saxitoxin as a chemical warfare agent. 4.3 Saxitoxin has been synthesised in very small quantities and with considerable difficulty. Saxitoxin was first synthesised in 1977 in a 17-step synthesis with an overall yield of 0.2%.8 More recently, saxitoxin has been synthesised in a 19-step synthesis with an overall yield of 1.6%.9 7 Websites. Because [3H]saxitoxin and native saxitoxin must have es-sentially identical binding constants at this site, the concen-tration of saxitoxin in the [3H]saxitoxin preparation can be de-termined by superimposing the two inhibition curves as in Fig. 1. Thus, 50% inhibition was obtained at 3.4 nM saxitoxin or at
