news@antikoerper-online.de (David Kitz Kramer) — Fri, 19 Mar 2010 14:34:00 +0100

Immunoglobulin E (IgE), and the interaction with it’s receptors expressed on mast cells and basophils, are main players in the pathomechanism of IgE mediated allergic reactions (allergic rhinitis, asthma, atopic dermatitis, food allergies). Purified human IgE protein, recombinant IgE receptors, and biochemically and functionally well characterized monoclonal antibodies, directed against different epitopes on these players, are tools of central importance for allergy research and diagnostics, and also for the identification and development of novel anti-allergic drugs.

news@antikoerper-online.de (David Kitz Kramer) — Fri, 19 Mar 2010 12:45:00 +0100

The transmembrane receptor TRAIL-R1 is a member of the TNF family and is being expressed in most human tissues. TRAIL-R1 has also been denominated death receptor (DR) 4 which derives from the pro-apoptotic action TRAIL-R1 exhibits.

The international congress Aseptic Surgery Forum 2010 focuses on the prevention and treatment of post-surgical infections.
The first edition of the meeting will be held on March 26 and 27 in Paris (France). It is aimed at promoting good surgical practices and technological innovations to cure and prevent post-surgical complications.

Bax: antibody against pro-apoptotic marker

news@antikoerper-online.de (David Kitz Kramer) — Thu, 18 Mar 2010 11:15:00 +0100

Bax can form homodimers, and also heterodimerizes with Bcl-2 and Bcl-XL proteins. This is possible because Bax is a member of the Bcl-2 family of apoptosis-associated proteins. Apoptosis can be induced by a variety of internal and external stimuli including growth factor deprivation, cytokine treatment, antigen-receptor engagement, cell-cell interactions, irradiation and glucocorticoid treatment.

Forkhead box protein N1 (FOXN1) antibody: key gene in human development

news@antikoerper-online.de (David Kitz Kramer) — Tue, 16 Mar 2010 12:55:00 +0100

The forkhead (named after the Drosophila melanogaster gene fork head) gene family comprises a diverse group of 'winged-helix' (called after its butterfly-like shape) transcription factors that play important roles in development, metabolism, cancer, ageing and speech development in humans.

Cancer diagnostics research: anti-Mitotic cells antibody

news@antikoerper-online.de (David Kitz Kramer) — Thu, 11 Mar 2010 15:35:00 +0100

The cell cycle of eukaryotic cells consists of various phases. Two of them can be identified morphologically and biochemically. The first phase that can be distinguished happens during cell mitosis (M-phase), in which the cell divides into two identical daughter cells; chromosome condensation and spindle formation are microscopically visible. The second discernible phase is the S-phase where the DNA of a cell is replicated. Antibodies recognizing the phases of the cell cycle are of value for example in cancer research.

Broadly applicable: Nitro Tyrosine Antibody

news@antikoerper-online.de (David Kitz Kramer) — Thu, 11 Mar 2010 15:08:00 +0100

Tyrosine nitration is a posttranslational modification generated by a nitrogen free radical (peroxinitrite ONOO^-). This reactive nitrogen specie reacts with macromolecules of the organism and alters their functions. This modification can lead to cell death during cell-stress conditions. Nitration is involved in many signalling pathways and plays a role in diverse research-areas ranging from Alzheimer's Disease over Immunology to Virology.

Frequently cited: Antibody detects antibacterial protein Cathelicidin

news@antikoerper-online.de (David Kitz Kramer) — Thu, 11 Mar 2010 11:40:00 +0100

Cathelicidin acts as effector of the innate immune system and possesses antimicrobial and immunomodulatory functions. Cathelicidin binds to bacterial lipopolysaccharides, and hence serves a critical role in the mammalian immune defence against bacterial infection. These peptides have been isolated from several species of mammals, and are part of a family of proteins situated in specific granules of polymorphonuclear leukocytes.

New research-area: Autophagy

news@antikoerper-online.de (David Kitz Kramer) — Wed, 10 Mar 2010 16:17:00 +0100

Autophagy is a cell-function that takes care of destruction and recycling of cell components. Thereby autophagy assures a balance between synthesis and catalysis of cell components. Autophagy is also part of the immune response, and belongs to the innate immune system. Malfunctions of autophagy can lead to development of various diseases. Now antibodies-online.com offers more than 140 antibodies for research in the field of autophagy.

New antibody: Enhanced Green Fluorescent Protein (EGFP) antibody

news@antikoerper-online.de (David Kitz Kramer) — Tue, 09 Mar 2010 16:27:00 +0100

The Enhanced Green Fluorescent Protein (EGFP) is a 29 kDa recombinant protein that emits fluorescent light of a wavelength of 488/507 nm. This Protein A purified rabbit polyclonal antibody detects EGFP and is specifically suitable for western blotting applications. In the 1960s and 1970s GFP was first purified from Aequorea victoria. It was not until the early 1990s that molecular biologists succeeded in utilizing wtGFP as a tool with multiple applications in genetics and molecular biology. EGFP has been optimized for brighter fluorescence and expression in mammalian cells.

Superior quality antibody: hsc70 (hsp-like) antibody frequently cited

news@antikoerper-online.de (David Kitz Kramer) — Tue, 09 Mar 2010 15:23:00 +0100

Heat shock proteins (HSP) support the maintenance of three dimensional structures of proteins for instance by protecting them from denaturation due to heat. They can be found everywhere in the organism and are expressed extensively, for example, under stress condition caused by exposure to high heat, UV-rays or ethanol.

Epigenetics tool: 5-Methylcytidine antibody

news@antikoerper-online.de (David Kitz Kramer) — Mon, 08 Mar 2010 14:23:00 +0100

This 5-methylcytidine (5meC or 5-MeCyd) antibody is a commonly use reference in epigenetic research that allows to detect methylation of cytidines. DNA methylation is a DNA modification process, which is involved in the control of gene expression, which leads to genes being silenced or enhanced in their expression having pre-recursions for a large variety of disorders. Recently, this part of genetics has become a vibrant research area that spans various fields of molecular biology and genetics. The importance of epigenetics lies in the fact that it has a great impact on the phenotype despite identical genotypes.

Recent study uses cystathionase antibody from antibodies-online.com

news@antikoerper-online.de (David Kitz Kramer) — Wed, 03 Mar 2010 17:40:00 +0100

Cancer cells have a high demand for cysteine as precursor of the antioxidant, glutathione, that is required to promote cell growth and division. The aim of a recent study by S Kandil, L Brennan, and GJ McBean, was to evaluate the relative contribution of different metabolic pathways to glutathione synthesis in astrocytoma/glioblastoma cells. The major finding was, that glutathione depletion causes a JNK- and p38MAPK -mediated increase in expression of cystathionine-γ-lyase that promotes flux through the transsulfuration pathway to compensate for loss of glutathione in C6 glioma cells. This study has been carried out with antibodies supplied by antibodies-online.com.

Frequently used: phospho-AKT1 monoclonal antibody

news@antikoerper-online.de (David Kitz Kramer) — Tue, 02 Mar 2010 11:39:00 +0100

There are three members in the AKT protein family in humans: AKT1, AKT2, and AKT3. These enzymes are members of the serine/threonine-specific protein kinase family. AKT1 (or AKT without numeral) regulates many downstream effectors. AKT1 is able to induce protein synthesis pathways, and is therefore a key signalling protein in the cellular pathways that lead to skeletal muscle hypertrophy, and general tissue growth.
