Creative Biolabs is a world’s leading service provider for bio-molecular interaction analysis. Our expert team offers the most professional solutions and the advanced technologies which will ensure the progress of our customers’ research. Our expertise including but not limited to identifying, analyzing, and validating the bio-molecular interactions and also the discovery of novel drug target.
The interactions between bio-molecules play key roles in many essential biological processes. While some proteins function independently, a large number of proteins are only active in complex forms, which are defined by their interactions with other biomolecules, such as proteins, DNAs, RNAs, lipids, and metals. The bio-molecular interaction not only describes the physical contact among protein partners but also expands to the functional correlations in metabolic pathways, signaling pathways and even genetic co-regulations. Bio-molecular interactions are essential in almost all the aspects of cellular processes, such as signal transduction, regulation of metabolic pathways, environment sensing, cellular motion. Therefore, understanding the contact between bio-molecules take place in fundamental cellular processes and how bio-molecule complexes function in a cellular network becomes increasingly important.
Protein-protein interactions (PPIs) as putative therapeutic targets for new treatments is challenging but gaining ground in the drug discovery industry for its significant progress in many diseases including cancer, cardiovascular disease and so on. Creative Biolabs has extensive experiences and advanced approaches on protein-protein interaction study. We could help you map the interacting network for your target proteins, validate the binding partners, and also design, discover and decipher the novel drugs.

In Creative Biolabs, the approaches for PPI detection are mainly classified into three types, in vivo, in vitro, and in silico methods. In vivo techniques include yeast two-hybrid system (Y2H), mammalian two-hybrid system (M2H), bacterial two-hybrid system (B2H), reverse two-hybrid system (rY2H), etc. For in vitro way, Co-immunoprecipitation (Co-IP), pull-down assay, protein-fragment complementation assay (PCA), phage display, X-ray crystallography, NMR spectroscopy, and surface plasmon resonance (SPR) can be offered. And in silico groups consist of text mining and computational analyses, are displayed on a computer or by computer simulation, involving gene fusion, sequence-based approaches, chromosome proximity, and so on.
Protein-nucleic acid interactions (PNIs) are fundamental for maintaining genome and reproducing life in central biological process ranging from DNA replication and repair to RNA packaging and maturation, recombination and transcription of DNA to translation and transport of RNA. These specific interactions are susceptible to monitor through several well-established analytical modes from Creative Biolabs involving biochemical, biophysical, genetic, and immunological techniques based on the diverse purpose of our clients.

In Creative Biolabs, in vitro services used for PNI contain electrophoretic mobility shift assay (EMSA), chromatin immunoprecipitation (ChIP), DNA/RNA pull-down, as well as other sensitive techniques such as aptamer by SELEX, X-ray crystallography, surface plasmon resonance (SPR), and NMR spectroscopy. For in vivo assays, there are yeast one-hybrid (Y1H), yeast three-hybrid (Y3H) and fluorescent resonance energy transfer (FRET). And the identification of PNI in silico is aided by sequence-based, structure-based, or other database and bioinformatics simulation through computational intelligence.
