CALIXAR patented technological platform allows the isolation in solution of full length and pure to highly pure membrane proteins – GPCRs, Ion Channels, Transporters, Receptors, Viral Proteins, … – while keeping their structural and functional integrity (no refolding step and no mutagenesis).
This innovative approach allowed the native isolation of membrane proteins which can be used for antibody development, vaccine formulation and/or drug discovery (FBDD, SBDD).
The following wild type and pure to highly pure purified membrane proteins are commercially available off-the-shelf:
A2A: Adenosine Receptor
A class A GPCR involved in regulating myocardial blood flow/hypertension, the regulation of glutamate and dopamine release. A2A is a good therapeutic candidate for insomnia, pain, depression, drug addiction and Parkinson’s disease. Protein has a N-terminal Step tag II and an 8X His tag followed by a TEV protease cleavage site.
MT1: Melatonine Receptor
Melatonin receptor 1 (MT1) is a class A GPCR that modulates neuronal firing, arterial vasoconstriction, cell proliferation in cancer cells, and reproductive and metabolic functions. MT1 is a good therapeutic candidate for insomnia, circadian sleep disorders, depression, cardiovascular regulation, cancer and neurodegenerative diseases. Protein has a strep tag II and 10X His tag at the N-terminus followed by a TEV protease cleavage site.
BmrA: Bacilus subtilis multidrug resistance ABC transporter ATP-binding Protein (BmrA) is an efflux protein and ABC transporter that acts as a mechanical pump for ATP dependent drug efflux. BmrA is a good target for multi-drug resistance studies. The protein has a N-terminal 6X His tag.
AcrB : Acriflavine resistance Protein B
Acriflavine resistance Protein B (AcrB) is a bacterial multidrug exporter. AcrB is a good target for indications of bacterial resistance. Protein has a C-terminal 6X His tag.
Nav1.7: Voltage-gated sodium channel
Voltage-gated sodium channel (Nav1.7) is involved in the generation and conduction of action potentials. Nav1.7 is a good candidate for pain indications. Protein has a C-terminal TEV cleavage site followed by a 10X His tag and a 2X Strep-Tag II.
