Abstract:
:Frauch's micro-slide method was improved to facilitate the endpoint-determination of the Limulus test. Two precise observations, by inverted phase contrast microscopy and with a staining procedure, were newly performed as additions to the slide test. The staining procedure was proposed as an improved method for the Limulus test since it is simple and convenient. In the staining method, bromophenol blue (BPB) solution was used as the staining solution. A negative (-), a strong positive (++) and a weak positive reaction (+) were characterized by a "ring" formation, a "cloud-like" spread of gel and a "spot" in the "cloud" respectively. Since the distinction between (-) and (+) reactions was obvious in the proposed method, determination of the endpoint was easier than in the ordinary tube and Frauch's method. The sensitivity of the present method was equal to or higher than that of other methods. Inverted phase contrast microscopy was utilized to confirm the findings obtained by the staining method. The volume of the lysate used in this method was as little as 1/10 of that used in the tube method.
