>95 % as determined by reducing SDS-PAGE.

Lyophilized from sterile PBS, pH 7.4, 5% Trehalose, 5% Mannitol, 0.01% Tween-80.

Samples are stable for up to twelve months from date of receipt at -70 degree C.Store it under sterile conditions at -20 degree C to -80 degree C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. Shipping: In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.

The recombinant human Fc/DPPIV is a disulfide-linked homodimeric protein.The reduced monomer consists of 975 amino acids and has a predicted molecular mass of 112 kDa. As a result of glycosylation, the apparent molecular mass of rhFc/DPPIV monomer is approximately 120-130 kDa in SDS-PAGE under reducing conditions.

Tag: N-Fc. Bio activity: 1. Measured by its ability to bind recombinant Cynomolgus CXCL12 in a functionalELISA. 2. Measured by its ability to bind recombinant Human SDF1b in a functionalELISA. 3. Using the Octet RED System, the affinity constant (Kd) of human Fc-DPPIV bound to Spike (HCoV-EMC/2012) was 11 nM. 4. Using the Octet RED System, the affinity constant (Kd) of human Fc-DPPIV bound to Spike (HCoV-EMC/2012) was 32 nM. 5. Using the Octet RED System, the affinity constant (Kd) of human Fc-DPPIV bound to Spike (HCoV-EMC/2012) (ECD, aa 1-1297) was 43 nM. 6. Using the Octet RED System, the affinity constant (Kd) of human Fc-DPPIV bound to Spike-His (aa 1-760) was 12 nM.

Endotoxin: < 1.0 EU per µg as determined by the LAL method. Reconstitution: It is recommended that sterile water(80 ul) be added to the vial to prepare a stock solution of 0.25 mg/mL. Concentration is measured by UV-Vis.

Background: Dipeptidyl peptidase-4 (DPP4) or adenosine deaminase complexing protein 2 (ADCP 2) or T-cell activation antigen CD26 is a serine exopeptidase belonging to the S9B protein family that cleaves X-proline dipeptides from the N-terminus of polypeptides, such as chemokines, neuropeptides, and peptide hormones. The enzyme is a type II transmembrane glycoprotein, expressed on the surface of many cell type s. It is also present in serum and other body fluids in a truncated form (sCD26/DPPIV). The soluble CD26 (sCD26) as a tumour marker for the detection of colorectal cancer (CRC) and advanced adenomas. As both a regulatory enzyme and a signalling factor, DPP4 has been evaluated and described in many studies. DPP4 inhibition results in increased blood concentration of the incretin hormones glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP). This causes an increase in glucose-dependent stimulation, resulting in a lowering of blood glucose levels. Recent studies have shown that DPP4 inhibitors can induce a significant reduction in glycosylated haemoglobin (HbA (1c)) levels, either as monotherapy or as a combination with other antidiabetic agents. Research has also demonstrated that DPP4 inhibitors portray a very low risk of hypoglycaemia development, and are a new pharmacological class of drugs for treating type 2 diabetes. Description: A DNA sequence encoding the extracellular domain (Asn 29-Pro 766) of the mature form of human DPPIV (NP_001926.2) was expressed with the fused Fc region of human IgG1 at the N-terminus.

The protein encoded by this gene is identical to adenosine deaminase complexing protein-2, and to the T-cell activation antigen CD26. It is an intrinsic membrane glycoprotein and a serine exopeptidase that cleaves X-proline dipeptides from the N-terminus of polypeptides. [provided by RefSeq, Jul 2008]

DPP4: Cell surface glycoprotein receptor involved in the costimulatory signal essential for T-cell receptor (TCR)-mediated T-cell activation. Acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. Its binding to CAV1 and CARD11 induces T-cell proliferation and NF- kappa-B activation in a T-cell receptor/CD3-dependent manner. Its interaction with ADA also regulates lymphocyte-epithelial cell adhesion. In association with FAP is involved in the pericellular proteolysis of the extracellular matrix (ECM), the migration and invasion of endothelial cells into the ECM. May be involved in the promotion of lymphatic endothelial cells adhesion, migration and tube formation. When overexpressed, enhanced cell proliferation, a process inhibited by GPC3. Acts also as a serine exopeptidase with a dipeptidyl peptidase activity that regulates various physiological processes by cleaving peptides in the circulation, including many chemokines, mitogenic growth factors, neuropeptides and peptide hormones. Removes N-terminal dipeptides sequentially from polypeptides having unsubstituted N-termini provided that the penultimate residue is proline. Belongs to the peptidase S9B family. DPPIV subfamily. Protein type: Cell adhesion; Cell surface; EC 3.4.14.5; Membrane protein, integral; Protease. Chromosomal Location of Human Ortholog: 2q24.2. Cellular Component: apical plasma membrane; cell surface; endocytic vesicle; focal adhesion; lamellipodium; lysosomal membrane; membrane; plasma membrane. Molecular Function: dipeptidyl-peptidase activity; identical protein binding; protease binding; protein binding; protein homodimerization activity; receptor binding; serine-type peptidase activity; viral receptor activity.
