Abstract

The isolated soluble eye proteins from six species (Sepia esculenta, Sepiella japonica, Loligo chinensis, Todarodes pacificus, Loligo beka and Ocotopus minor) of class Cephaloopoda were compared by crossed immunoelectrophoresis methods using antibodies directed against total soluble eye proteins antigens. It showed a distinct antigen-antibody reaction between the species of order Sepioidea and various antiserum of class Cephalopoda. Our results suggested that the common precipitation lines of Sepia and Loligo species which were different from that of Octopus minor. By which obtained from elution of gel filtration chromatography and 12.5% SDS-polyacrylamide gel electrophoresis, the molecular weight of Todarodes pacificus eye protein (crystallin) was determined in abut 20-35 KDa.

황해산 두족류 6종(참갑오징어, Sepia esculenta ; 쇠갑오징어, Sepiella japonica : 한치꼴뚜기, Loligo chinensis : 살오징어, Todarodes pacificus : 참꼴뚜기, Loligo beka : 낙지, Octopus minor)의 안구단백질을 추출하여 항원-항체 교차반응을 실시하였다. 쇠갑오징어, 살오징어와 낙지의 안구단백질로 항혈청(antiserum)을 제작하였으며 갑오징어목, 살오징어목 및 낙지목에 속하는 두족류 6종의 안구단백질을 항원(antigen)으로 사용하였다. 갑오징어목 속하는 쇠갑오징어 및 참갑오징어에서 항원-항체 반응 양상이 매우 뚜렷하였으며 종간 비교에 기준이 될 수 있고 또한 유의성있는 침강선을 볼 수 있었다. 또한 gel filtration chromatography 방법으로 살오징어의 안구단백질을 분획하여 crystallin을 분리하였으며, 주 분획을 SDS-PAGE 전기영동 방법으로 분자량을 추정해 본 결과 약 20-35 KDa 였다.
