Human Recombinant ACE2 Protein, aa18-740 (HEK293-expressed)

Supplier: STEMCELL Technologies
Description: Human Recombinant Angiotensin-Converting Enzyme 2 (ACE2) Protein, aa18-740, is expressed in HEK293 cells. ACE2 activity results in vasodilation by degrading vasoconstrictor angiotensin II to produce vasodilator angiotensin. Decreased expression of this enzyme is associated with cardiovascular disease and possibly also glomerular injury in diabetic nephropathy. ACE2 contains a peptidase domain at the N-terminus and a single transmembrane helix. ACE2 is also the primary human receptor for the surface spike glycoprotein of SARS-CoV-2 and SARS-CoV. This receptor is expressed in human lung and small intestine epithelia as well as the heart, kidney, and testes. The peptidase domain of ACE2 binds to the protein-binding domain of the S1 protein subunit of the spike protein; this binding results in a cleavage site becoming exposed. Cleavage, or ‘protein priming’, is done by TMPRSS2, a cellular serine protease, and by cathepsins. This cleavage activates the S2 subunit of the spike protein, allowing the fusion of the viral membrane to the host cell membrane. At the carboxy terminus, Human Recombinant ACE2 Protein contains a TEV site and a human IgG1 Fc tag.

SARS-CoV-2 Recombinant Nucleocapsid Protein, aa1-419 (HEK293-expressed)

Supplier: STEMCELL Technologies
Description: SARS-CoV-2 Recombinant Nucleocapsid Protein, aa1-419 is expressed in HEK293 cells and is one of four structural proteins encoded by the SARS-CoV-2 genome. The Nucleocapsid Protein is transcribed from the viral “N” gene and is the protein that interacts with RNA to form the nucleocapsid. The protein forms a homo-oligomer, and both the monomer and the oligomer can interact with RNA. This protein also interacts with the membrane protein (protein M) after infection of the host cell during packaging of the positive-strand viral genome RNA into the ribonucleocapsid during virion assembly.

SARS-CoV-2 Recombinant Nucleocapsid Protein, aa1-419 (E. coli expressed)

Supplier: STEMCELL Technologies
Description: SARS-CoV-2 Recombinant Nucleocapsid Protein, aa1-419 is expressed in <i>E. coli</i> and is one of four structural proteins encoded by the SARS-CoV-2 genome. The Nucleocapsid Protein is transcribed from the viral “N” gene and is the protein that interacts with RNA to form the nucleocapsid. The protein is a homo-oligomer, and both the monomer and the oligomer can interact with RNA. This protein also interacts with the membrane protein (protein M) after infection of the host cell during packaging of the positive-strand viral genome RNA into the ribonucleocapsid during virion assembly. At the amino terminus, SARS-CoV-2 Recombinant Nucleocapsid Protein contains a thrombin site, a T7 tag, and a polyhistidine tag.

SARS-CoV-2 Recombinant Spike Protein, aa319-541 (Yeast-expressed), His Tag

Supplier: STEMCELL Technologies
Description: SARS-CoV-2 Recombinant Spike Protein, aa319-541 is expressed in <i>Pichia pastoris</i> and is one of four structural proteins encoded by the SARS-CoV-2 genome. The Spike Protein plays a key role in attachment to host cells allowing invasion through clathrin-mediated endocytosis. The spike protein can be cleaved by host cell proteases after aa685 to yield the N-terminal S1 subunit, and C-terminal S2 region. The S1 subunit is responsible for interacting with the host cell receptor (angiotensin-converting enzyme II) through a receptor-binding domain that is highly conserved with SARS-CoV. The S1 subunit has two conformations: a ‘down’ conformation in which the receptor is inaccessible, and an ‘up’ conformation in which the receptor is accessible. These conformational changes are key for monoclonal antibody drugs and vaccine development. At the amino terminus of the polypeptide chain, SARS-CoV-2 Recombinant spike protein contains a polyhistidine tag and a SUMOstar site.

SARS-CoV-2 Recombinant Spike Protein, aa16-685 (HEK293-expressed), FLAG and His tags

Supplier: STEMCELL Technologies
Description: SARS-CoV-2 Recombinant Spike Protein, aa16-685 is expressed in HEK293 cells and is one of four structural proteins encoded by the SARS-CoV-2 genome.

Recombinant Protein G

Supplier: Apollo Scientific
Description: Recombinant Protein G

Recombinant Protein G (from E. coli)

Catalog Number: (PRSI96-655)
Supplier: ProSci Inc.
Description: Protein G is an immunoglobulin-binding protein expressed in group C and G Streptococcal bacteria much like Protein A but with differing specificities. It is a 65-kDa (G148 protein G) and a 58 kDa (C40 protein G) cell surface protein that has found application in purifying antibodies through its binding to the Fc region. The native molecule also binds albumin, however, because serum albumin is a major contaminant of antibody sources, the albumin binding site has been removed from this recombinant form of Protein G.
UOM: 1 * 2 mg

Human Recombinant G-CSF (E.coli-expressed)

Supplier: STEMCELL Technologies
Description: Granulocyte colony-stimulating factor (G-CSF) is a member of the CSF family of glycoproteins that regulate hematopoietic cell proliferation, differentiation, and function. It is a key cytokine involved in the production of neutrophils and the stimulation of granulocyte colony formation from hematopoietic progenitor cells (Metcalf andamp; Nicola). G-CSF causes a range of effects including a transient reduction of SDF-1 expression (Petit <i>et al.</i>), the activation of metalloproteases that cleave VCAM-1 (Levesque <i>et al.</i>), and the release of norepinephrine from the sympathetic nervous system (Katayama <i>et al.</i>), leading to the release or mobilisation of hematopoietic stem cells from the bone marrow into the periphery. The G-CSF receptor is expressed on a variety of hematopoietic cells, including myeloid-committed progenitor cells, neutrophils, granulocytes, and monocytes. In addition to hematopoietic cells, G-CSF is also expressed in cardiomyocytes, neuronal cells, mesothelial cells, and endothelial cells. Binding of G-CSF to its receptor leads to activation of the JAK/STAT, MAPK, PI3K, and AKT signal transduction pathways.

Protein reducing agents

Supplier: G-Biosciences
Description: Protein-S-S-Reductant™ uses TCEP (Tris [2-carboxyethyl] phosphine), a popular alternative to β-mercaptoethanol and DTT (dithiothreitol). TCEP improves stability, increases effectiveness, and reduces proteins over a wider range of pH, including lower acidic pHs. Protein-S-S-Reductant™ completely reduces stable disulfide bonds in less than 5 minutes at room temperature and is compatible with the protein alkylation reactions. This ready to use solution is at a neutral pH and stabilised for long-term storage. Simply supplement Protein-S-S-Reductant™ in place of DTT or β-mercaptoethanol and boil the sample.
