All PGA4 reagents are produced in house and quality controlled, including 2 PGA4 Antibody, 13 PGA4 Gene, 2 PGA4 Lysate, 2 PGA4 Protein, 1 PGA4 qPCR. All PGA4 reagents are ready to use.
Recombinant PGA4 proteins are expressed by HEK293 Cells with fusion tags as C-human IgG1-Fc, C-His.
PGA4antibodies are validated with different applications, which are ELISA, IHC-P.
PGA4cDNA clones are full length sequence confirmed and expression validated. There are 13 kinds of tags for each PGA4 of different species, especially GFP tag, OFP tag, FLAG tag and so on. There are three kinds of vectors for choice, cloning vector, expression vector and lentivrial expression vector.
PGA4 (Pepsinogen 4, group I), or Pepsinogen A, is a member of the peptidase A1 family. Pepsin is expressed as a pro-form zymogen, pepsinogen, whose primary structure has an additional 44 amino acids. Pepsin is stored as pepsinogen so it will only be released when needed, and does not digest the body's own proteins in the stomach's lining. Five types of zymogens of pepsins, gastric digestive proteinases, are known: pepsinogens A, B, and F, progastricsin, and prochymosin. There are two major groups of pepsinogen, namely pepsinogen A (PGA) and pepsinogen C (PGC) (or progastricsin), and each frequently has isozymogens. The PGA3, PGA4 and PGA5 genes encode identical human pepsinogen A enzymes.
