The recently discovered FTO (Fat mass and obesity orientated) gene is of great interest to antibody research groups, throwing clearer insight into the reasons why some people have difficulty losing weight, even when following a healthy lifestyle.

We at Novus Biologicals have a large antibody database for cancer research. However, AML, or acute myeloid leukaemia, is one of the cancers for which the number of antibodies is still fairly small, owing to limited knowledge of the genes involved.

Human derived antibodies are widely used in disease research. These tend to be associated with cancer cell lines, such as the MCF7 breast tumour line, for which we provide both antibodies and whole cell lysate. The cells that are generated are identical in every respect to the originals, meaning reproducible results can be obtained years after the original cell lines were harvested.

At Novus Biologicals, we have over 9,000 products on our transduction antibody database. Signal transducers are proteins that facilitate movement of signals, i.e. molecules that cause a reaction, from outside to inside the cell, where they cause changes to cellular function and activity in either the cytoplasm or the nucleus. Transduction pathways are usually activated by complex enzyme cascades, and new proteins are constantly being developed. Thus, our antibody catalogue is constantly being updated.

We at Novus Biologicals have a number of products in our antibody catalog covering the area of circadian rhythms. Disruptions of the "biological clock" mechanism are known to cause a range of disorders.

We at Novus Biologicals are constantly creating new stem cell lines for a variety of bioassays – they are an essential part of our antibody catalog. Although stem cells are derived from many types of tissue, both adult and human, there is much controversy over their use.

Tumor necrosis factor alpha has been shown to be important in the cellular response to chronic heart failure, with signaling taking place through the receptor isotypes TNFR1 and TNFR2. We at Novus Biologicals have a large number of TNF-related antibodies in our database. Many of today's studies are based on information gained by Defer et al. in 2007.

The CD44 family comprises a number of immunologically similar glycoproteins, which are expressed on the membranes of endothelial, mesenchymal, leukocyte and hepatocyte cells. The CD44 family has a number of functions. CD44 antibody assays have shown some that some isoforms play a role in abnormal gene splicing in human cells.

We at Novus Biologicals have a large number of products in our antibody database which are used for metabolic research. A new Adropin antibody is a recent addition, and is used in obesity research. Although not life-threatening in its own right, obesity – as we all know - can lead to a host of more serious illnesses including heart disease, stroke and diabetes.

Embryonic stem cells (ESCs) and their corresponding marker antibodies are often used in cancer research, since cell-renewal is a feature shared by both ESCs and cancer cells. The drawback is that there is no clear evidence of a transcription program common to both cell types. However, in a study (Wong et al. 2008), it was described how comparison of human and murine ESC-like gene modules had isolated a catalog of 335 genes, which could be used as a "core ESC-like gene module" for tumor studies.
