Corporate Overview
SignalChem has established itself as a leader in the development of innovative cell signaling products to
meet the needs of scientist in basic research and drug discovery. The company has utilized its core
capabilities of cellular signaling, molecular biology and protein biochemistry to generate more than 500
products as part of its current and continuously expanding product portfolio. One area of particular
strength for the company is the production of highly purified human recombinant enzyme and protein
targets. With this ever expanding library of enzymes and protein targets, SignalChem has invested
additional resources to perform profiling of compounds as well as the production and validation if high
quality isoform specific antibodies which are intended to recognize a single target; the protein of
interest. We are pleased to provide our clients with access to high quality validated cell signaling
products and compound profiling service.
Our current PRODUCT OFFERING encompasses enzymes, signaling proteins and antibodies.
Enzymes
In basic research and drug discovery, enzymes possessing catalytic activity are essential bait in drug
discovery and have been extensively used in identifying specific compounds which inhibit or activate a given
target; these compounds could eventually make their way into the clinic and be used for the treatment of various
human diseases.
Within the Enzymes category, we currently offer:
Active Protein Kinases
Protein kinases are key mediators of cellular communication; this is achieved through the
phosphorylation of key amino acids including serine, threonine and tyrosine. Targeting protein
kinases has been extremely beneficial in the treatment of various human diseases and more than
10 drugs targeting protein kinases have been approved. We offer serine/threonine kinases, receptor
tyrosine kinases, cytoplasmic tyrosine kinases and lipid kinases.
Active Protein Phosphatases
Protein phosphatases in general antagonize the effects of protein kinases through dephosphorylation
of specific amino acids. Recently, this class of enzymes has been deemed to be important as drug
targets for the treatment of various human diseases such as diabetes and cancer.
Active Phosphodiesterases
Phosphodiesterases represent important therapeutic targets in the treatment of various disease settings
including inflammatory conditions, cardiovascular disease and neurological disorders like dementia as
well as erectile dysfunction. To date, 7 different PDE inhibitors have been approved for use in the clinic.
Cell Signaling Reagents
Cellular communication is influenced by both extra- and intra-cellular factors that can modulate or
regulate specific signaling cascades in both a positive and negative manner.
Within the Signaling Reagents category, we currently offer:
Cellular Proteins
Cellular proteins represent cell signaling intermediates, adaptor proteins, scaffolding proteins,
molecular chaperones and transcription factors; these proteins are involved in the regulation of
various biological processes including protein expression, cellular proliferation, oxidative stress,
and apoptosis amongst others.
Peptide Substrates
Biologically active enzymes like kinases mediate their effects by specifically interacting with a
given substrate and modifying them accordingly. The interaction between an enzyme and its cognate
substrate(s) is highly precise and is known to occur on very specific amino acids. Based on this
information, small synthetic peptides can be utilized in assaying specific enzymatic activity.
Reagents
Enzymes require optimal conditions for maximal activity. Based on this specific requirement, we
have produced very specific buffers to accompany our active enzymes so that researchers using
our products achieve the best possible results.
Unactive Kinases
Unactive kinases represent enzymes which possess minimal or no biological activity; these types
of reagents are often used in validation type of studies in drug discovery.
Antibodies
Antibodies are very important components in human biology; they have also aided in the quest
to investigate the inner workings of a cell.
Within the Antibodies category, we currently offer:
Isoform Specific Antibodies
Access to highly validated biological ’reagents’ is of paramount importance in research
and drug discovery. We are pleased to offer researchers a unique line of highly validated isoform
specific antibodies that specifically recognize the intended target with the greatest affinity. All
of these antibodies are counter-screened against the recombinant isoforms that SignalChem offers as
a means of ensuring true specificity.
Primary Antibodies
To better serve the needs of researchers worldwide, and to complement our recombinant protein offering,
we now offer monoclonal and polyclonal antibodies against many of our recombinant proteins.
Secondary Antibodies
To further service the needs of researchers and to minimize ordering efforts, we offer secondary
antibodies to assist you with your research needs.
Tag Antibodies
In cell based studies, many proteins are expressed with ’tags’ as these tags aid in
establishing whether a target is expressed, at what level it is expressed and where it is localized.
Further, these tags can aid in purification. To serve your needs in this area, we have developed a
line of tag specific antibodies that can be utilized across various applications.
Our current SERVICE OFFERING includes compound selectivity profiling
and custom protein development.
Compound Selectivity Profiling
SignalChem's compound selectivity profiling service utilizes a large and diverse panel of
highly active protein kinase, phosphatase and phosphodiesterase targets that are produced
internally. We offer a variety of screening services that can be customized to meet your
specific research needs.
Custom Protein Development
SignalChem scientists will work with you to custom develop your target to the desired specifications.
