简介
The DEFA1 protein is a multifunctional effector in innate immunity that exhibits antibiotic-like properties against bacteria, fungi, and viruses. It promotes immune defense by activating antigen-presenting cells (APCs) and inhibiting bacterial cell wall synthesis by interacting with lipid II. DEFA1 Protein, Human (HEK293, Twin Strep) is the recombinant human-derived DEFA1 protein, expressed by HEK293, with C-Twin-Strep labeled tag.

稳定性测试
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Protein Description
Defensins are a class of small, cationic peptides that play critical roles in the innate immune response, and among them, DEFA1 is a member of the human alpha-defensin family. DEFA1 is primarily expressed in neutrophils and is known for its antimicrobial properties, particularly against bacteria and fungi. Research on DEFA1 is particularly relevant due to its potential implications in understanding host defense mechanisms, inflammatory responses, and the development of novel therapeutic agents. The study of DEFA1 recombining proteins involves expressing the gene in laboratory settings to produce the protein in sufficient quantities for detailed analysis. This research aims to elucidate the structural and functional characteristics of DEFA1, allowing for better insights into its antimicrobial mechanisms and interactions with pathogens. Additionally, the exploration of DEFA1 variants can provide information on genetic factors that influence susceptibility to infections and diseases. As antibiotic resistance continues to pose a significant public health challenge, DEFA1 and other defensins are being investigated for their potential as alternative antimicrobial agents. The ongoing research in the field of DEFA1 recombinant proteins underscores its significance in linking basic immunology with translational medicine, aiming to harness the natural defense mechanisms for therapeutic applications.
