Defensin Alpha 4 Recombinant Protein | DEFa4 recombinant protein
Recombinant Defensin Alpha 4, Corticostatin (DEFa4)
Stability Test: The thermal stability is described by the loss rate of the targetprotein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 degree C for 48h, and no obvious degradation andprecipitation were observed. The loss of this protein is less than 5% within the expiration date under appropriate storage condition.

NCBI and Uniprot Product Information
NCBI Description
Defensins are a family of antimicrobial and cytotoxic peptides thought to be involved in host defense. They are abundant in the granules of neutrophils and also found in the epithelia of mucosal surfaces such as those of the intestine, respiratory tract, urinary tract, and vagina. Members of the defensin family are highly similar in protein sequence and distinguished by a conserved cysteine motif. Several alpha defensin genes are clustered on chromosome 8. This gene differs from other genes of this family by an extra 83-base segment that is apparently the result of a recent duplication within the coding region. The protein encoded by this gene, defensin, alpha 4, is found in the neutrophils; it exhibits corticostatic activity and inhibits corticotropin stimulated corticosterone production.

Uniprot Description
DEFA4: Has antimicrobial activity against Gram-negative bacteria, and to a lesser extent also against Gram-positive bacteria and fungi. Protects blood cells against infection with HIV-1 (in vitro). Inhibits corticotropin (ACTH)-stimulated corticosterone production. Belongs to the alpha-defensin family.

Product Notes
The DEFa4 defa4 (Catalog #AAA2030626) is a Recombinant Protein produced from E.coli and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's Defensin Alpha 4 can be used in a range of immunoassay formats including, but not limited to, Positive Control; Immunogen; SDS-PAGE; WB. Researchers should empirically determine the suitability of the DEFa4 defa4 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. The amino acid sequence is listed below: QARGDEAP GQEQRGPEDQ DISISFAWDK SSALQVSGST RGMVCSCRLV FCRRTELRVG NCLIGGVSFT YCCTRVD. It is sometimes possible for the material contained within the vial of "Defensin Alpha 4, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
