Abstract: The invention is directed to a method and kit to control and modify the status of cells, such as human stem cells, by changing their glycosylation, in particular sialylation and fucosylation, levels in a reaction condition where culture medium reagents, such as divalent cations, are present and cells are kept non-adherent. The invention is further directed to novel stem cells, the glycosylation of which has been specifically altered.

Abstract: The invention is directed to the analysis of novel acidic glycan markers of several types of human cells. The analysis is performed by mass spectrometry or specific binder molecules.

Abstract: This invention relates to antibody engineering technology. More particularly, the present invention relates to human IgM antibodies and derivatives thereof, which have novel binding specificity with regard to several oligosaccharide sequences and/or xenoantigenic sialic acid residue. The present invention also relates to processes for making and engineering such novel saccharide and/or NeuGc-binding monoclonal antibodies and to methods for using these antibodies and derivatives thereof in the field of immunodiagnostics, enabling qualitative and quantitative determination of xenoantigenic NeuGc in biological and raw material samples, as well as in immunotherapy, enabling blocking of xenoantigenic NeuGc in patients.

Abstract: The invention relates to a method for culturing human embryonic stem cells (hESCs) with a lectin. The invention relates also to the use of a lectin in a method for culturing human embryonic stem cells (hESCs) and a culture medium composition containing a lectin.

Abstract: The present invention provides methods and materials to modulate and grow stem cells by contacting stem cells with a binder recognizing terminal glycan structures of stem cells. The modulation can be morphological change, change in differentiation status, biological status or adherence. The materials provided in the present invention are also useful to screen such a binding agents and binders.

Abstract: The present invention relates to a method of profiling a cell population comprising a step of detecting the presence or absence of at least two biological markers in said cell population, wherein at least one of said markers is a cell surface marker, which is a sialylated N-glycan marker with structure NeuNAc?3Gal, and at least one of said markers is a mRNA marker related to glycoproteins and/or glycosynthase proteins. The invention also relates to method for purification of cord blood cell population and to a complete cell population from cord blood purified by said method.

Abstract: Process for preparing a purified immunoglobulin preparation. The process comprises the steps of subjecting a crude immunoglobulin solution to caprylic acid treatment, removing protein aggregates and viruses from the immunoglobulin solution, subjecting the immunoglobulin solution to anion exchange chromatography in order to purify the immunoglobulin, filtering the immunoglobulin solution thus obtained on a virus-removal filter to produce an eluate containing immunoglobulin, and recovering the immunoglobulin. By combining caprylic acid treatment and precipitation with a protein precipitant the level of aggregated proteins and viruses is effectively reduced and a truly virus safe preparation is provided after filtration.

Abstract: The present invention comprises a method of protecting organs or tissue susceptible to reperfusion-induced dysfunction after ischemia. The method comprises parenterally administering to a patient a therapeutical composition containing natural alpha-1 acid glycoprotein, natural alpha-1 antitrypsin or a mixture thereof. Alternatively, organ or tissue transplants can be contacted with natural alpha-1 acid glycoprotein, natural alpha-antitrypsin or mixtures by perfusing or flushing them with a solution containing natural alpha-1 acid glycoprotein, natural alpha-1 antitrypsin or mixtures thereof in a concentration of 0.1 to 5 g/l.

Abstract: The present invention relates to pharmaceutical compositions of transferrin and to the manufacture of such preparations. The present invention concerns specifically a pharmaceutical composition of apotransferrin, the iron-free form of transferrin, wherein the composition has at least 90% of the theoretical iron binding capacity of iron-free transferrin, contains less than 3% transferrin dimers and no detectable transferrin polymers or aggregates, and has an iron-saturation of less than 5%. The pharmaceutical apotransferrin composition of this invention effectively binds non-transferrin-bound-iron to a harmless form when administered as an intravenous injection or infusion to patients. The pharmaceutical composition of this invention does not contain viruses, denatured forms of transferrin or other harmful components.
