Title: [Preparation and characterization of monoclonal antibody against human LSECtin]. Author: Du XM, Tang L, Liu XL, Chen Y, Gao JE, He FC, Sun QH. Journal: Xi Bao Yu Fen Zi Mian Yi Xue Za Zhi; 2006 Jul; 22(4):517-20. PubMed ID: 16806021. Abstract: AIM: To prepare and characterize monoclonal antibody (mAb) against human LSECtin (liver and lymph node sinusoidal endothelial cell C-type lectin) protein. METHODS: BALB/c mice were immunized with prokaryotically expressed human LSECtin protein. The splenocytes from the immunized mice were fused with murine myeloma cells (Sp2/0) and then the mAb-positive hybridoma cells were screened by indirect ELISA. Reaction of mAb to LSECtin antigen was characterized by Western blot, indirect immunofluorescent staining, immunohistochemical staining and FCM. RESULTS: Eight hybridoma cells secreting mAbs were established. The isotypes of the mAbs were IgG. Ascites titers were between 1:10(6) - 1:10(7). All the mAbs recognized human LSECtin protein on LSECtin-transfected 3T3 cells and six of the mAbs specifically recognized liver sinusoidal endothelial cells. CONCLUSION: Eight anti-LSECtin mAbs have been obtained. The characterization of the mAbs indicate that they show fine specificity by Western blot, indirect immunofluorescent staining, immunohistochemical staining and FCM, which can provide a powerful reagent for the functional study of LSECtin.[Abstract] [Full Text] [Related] [New Search]
