Haemagglutinins from the Slug Limax flavus

Haemagglutinins from some British Non-Marine Mollusca

“…These results are in contrast to those obtained by Pemberton [16] from Limax flavus, whose agglutinins were slightly inhibited by lactose, melibiose, raffinose, sucrose and trehalose only. Evidently the non-specific agglutinins of Arion ater, Limax flavus and L. maxi mus are individually chemically dissimilar, and the two latter ap parently do not bear an especial relationship to each other.…”

“…However, whereas the Arion ater agglutinins could be completely inactivated at 60 °C, such treatment only partially inhibited the activity of Limax maximus extract. In this respect at least, the L. maximus agglutinins resemble those of L. flavus [16].…”

“…A limited number of haemagglutination-inbibition tests were car ried out with Arion ater and Limax maximus extracts against certain simple sugars, in order to compare the apparently non-specific ag glutinins present in arionid and limacid slugs; more particularly between the Arion ater sample taken from the same locality at Dor king as the specimens of Limax flavus examined by Pemberton [16].…”

“…The results of investigations on belicid snails have been reviewed by Prokop et al [19]. Agglutinins from other non-marine molluscs have been reported by Brain and Grace [2], Gibb et al [5], Gold et al [7], Gold and Thompson [8], Khalap et al [10,11], and Pemberton [14,15,16].…”

NATURALLY-OCCURRING HEMAGGLUTININ IN A TUNICATE HALOCYNTHIA PYRIFORMIS

“…A resurgence of interest in these factors has taken place recently, largely as a result of their implication as a part of a system for the recognition of foreign antigens (Boyden, 1966; Tripp, 1966;Cushing, 1967) and because of the unusual properties of plant lectins already mentioned. Recently natural hemagglutinins have been reported in numerous invertebrates including sponges (Gold, Phelps, Khalap and Balding, 1974), pelecypod mollusks (Jenkin and Rowley, 1970;Acton, Bennett, Evans and Schrohenloher, 1969;Cornick and Stewart, 1973), gastropod mollusks (Pemberton, 1970a;1970b;Bizot, 1971;Hammarstrom and Kabat, 1971;Matsubara and Boyd, 1974;Pauley, Granger and Krassner, 1971); annelids (Cooper, Lemmi and Moore, 1974); arthropods (Miller, Ballback, Pauley and Krassner, 1972;Marchalonis and Edelman, 1968;Finstad, Litman, Finstad and Good, 1972;Pauley, 1973;Scott, 1971;Anderson, Day and Good, 1972), and echinoderms (Finstad, Litman, Finstad and Good, 1972). Halocynthia hemagglutinin was assayed in hemolymph cleared of blood cells by centrifugation.…”
