Monoclonal antibodies distinguish subtypes of retinal horizontal cells.

چکیده
Sixteen hybridomas have been identified that secrete antibodies specific to horizontal cells in the carp retina. The hybridomas have been classified into three groups based on their antibody staining patterns: group I, staining associated with all horizontal cells; group II, staining associated with the most abundant subtype of horizontal cell (CH1); and group III, staining associated with other subtypes of horizontal cells. Most of the hybridomas fall in group II; some of these antibodies stain the entire horizontal cell, but others are specific only to the cell perikarya and do not stain axonal processes. Our results suggest that there are surface molecules specific (i) to all retinal horizontal cells, (ii) to individual subtypes of horizontal cells, and (iii) to portions of horizontal cells. Furthermore, a group II antibody, which recognizes a 48- to 50-kDa membrane protein, has been found to provide a substrate selective for horizontal cell growth. Horizontal cells plated on coverslips coated with this antibody remain healthy in culture and extend long and elaborate processes for at least 3 weeks.

Monoclonal Antibodies
SUMMARY Monoclonal Antibodies are identical antibodies and Can be generated in ultimated amounts by countinuos cultures of single antibody- secreting cells. These cell lines are produced by cell fusion of normal lymphocytes to cells of a myeloma tumor cell line, which confers on the antibody producing hybrid cell, immortality and the ability grow as atumor in animals. monoclonal antibodies c...
متن کاملAnti-CD19 Monoclonal Antibodies: a New Approach to Lymphoma Therapy
CD19 is expressed on B- lineage cells and follicular dendritic cells and plays a key role in B cell malignancies and autoimmune diseases. Thus, it has been considered as potential target for several monoclonal antibodies (mAbs). For decades, chemotherapy has been known as one of the major antitumor therapies eradicating high proliferative tumor cells. But, anti- CD19 mAbs developed for treating...
متن کاملDevelopment of monoclonal antibodies against axenic amastigotes of Leishmania infantum strain in Iran: Implication for diagnosis of Kala-azar
Objective(s): Leishmaniasis is endemic in 88 countries. Amastigote forms of Leishmania are experts at exploiting host cell processes to establish infection. Monoclonal antibodies are key reagents used in the diagnosis of infectious and non-infectious diseases. The aim of this study was to produce monoclonal antibodies against axenic amastigotes of the Leishmania infantum strain in Iran.Material...

Background & Aims: Nowadays, by advent of hybridoma technology in monoclonal antibodies production various cell markers could be evaluated in malignant and non-malignant cells. CD20, non-glycosylated phosphoprotein is as an ideal marker in leukemia and B-cell lymphoma diagnosis which is expressed on more than 95% of normal and neoplastic B-cells except for early B-cells and mature plasma. Th...
متن کاملTHE PRODUCTION OF MURINE MONOCLONAL ANTIBODIES (MAb) DIRECTED AGAINST HUMAN T- LYMPHOCYTE SUBSETS
The production of murine monoclonal antibody (MAb) has not yet been reported in Iran. The present work describes for the first time the generation of several murine hybridoma clones secreting MAbs directed against human leukocyte surface antigens. The secreted antibodies by hybridoma clones have been screened on different lymphoid and non-lymphoid tissues. Results indicated that of seven h...
