摘要:
The invention relates to the use of optimised human or humanised chimeric monoclonal antibodies which are produced cell lines, said antibodies having a strong affinity for receptor CD16 of the effector cells of the immune system and being able to induce the secretion of cytokines and interleukins, in particular 1′ IFN? or 1′ IL2, for the treatment of pathologies for which the target cells only express a low antigenic density and in which the effector cells can only be recruited in small quantities.
摘要:
Methods for producing immunoglobulins and in particular anti-D immunoglobulin substantially free of virus and product resulting therefrom. Specifically provided are methods for nanofiltration of the anti-D immunoglobulin in high ionic strength buffer and with excipient such as polysorbate 80. Additional steps include diafiltration to concentrate the anti-D protein and reduce the concentration of excipient present.
摘要:
This invention provides for recombinant single chain antibodies capable of specifically binding to a Lewis.sup.Y -related carbohydrate antigen and fusion proteins comprising these antibodies. More particularly, the invention provides for single chain Fv regions of the monoclonal antibody B3. The invention also provides for a method of improving the binding affinity of antibodies lacking a serine at position 95 of the V.sub.H region that involves mutating position 95 to a serine.
摘要:
The genes defining the ABO histo-blood groups are disclosed. Methods for identification of histo-blood group ABO status are provided. The methods include the use of DNA probes or size separation of DNA fragments unique to a blood group status. The present invention also discloses DNA constructs, recombinant methods for providing histo-blood glycosyltransferases, methods for tumor suppression, purified histo-blood group glycosyltransferases, and antibodies produced therefrom which bind to protein epitopes.
摘要:
A monoclonal antibody which identifies the human blood group Duffy (ab) is provided. Such monoclonal antibody blocks the penetration of P. vivax malaria parasite into human red blood cells by virtue of effective blocking of the target molecule of the P. vivax malaria parasite. Such monoclonal antibody has a combining site having the same stereochemistry as the ligand site on P. vivax, and elicits anti-idiotypic antibodies that react with the parasite.

摘要:
A method for distinguishing between carcinomatous and/or precarcinomatous colo-rectal disease and histologically similar conditions due to diseases that are not carcinomatous or precarcinomatous comprising contacting colo-rectal tissue with an antibody that binds to blood group substance H and determining the presence of carcinomatous or precarcinomatous disease upon a finding of bound antibody, or the absence of such disease upon the finding of no bound antibody.
摘要:
The present invention relates to antigens present in blood group A and blood group AB erythrocytes but absent in blood group B and blood group O erythrocytes. More specifically, the present invention relates to A-associated H-antigens having the following structure: ##STR1## wherein X is a sugar residue and n=0 or a positive integer and wherein R is a primary amino group containing material selected from the group consisting of a polypeptide, a primary amino group containing liquid and a primary amino group containing support; monoclonal antibodies specific thereto and methods for employing the same in blood typing.
摘要:
Cloned mouse hybridoma cell lines have been established which continuously produce antibodies that are highly specific to and exhibit high affinity for glycophorin A.sup.N and differentiate between the M and N forms of human glycophorin A.
摘要:
An assay for determining the Lewis blood group of a patient consists of testing a body sample for the presence of Lewis.sup.a and Lewis.sup.b antigens. Monoclonal antibodies specific for either of these antigens are employed which do not cross-react with other related antigens, such as the H blood antigen. Body samples which may be tested include: saliva, serum, urine, and paraffin-embedded tissue samples. Hybridoma cell lines and the antibody compositions they produce specific for these antigens are provided for use in the assay.
