Human IL-1 alpha / IL-1F1 Protein, premium grade

分子别名(Synonym)

IL1A,IL-1 ALPHA,IL1F1,IL1α

表达区间及表达系统(Source)

Human IL-1 alpha Protein, premium grade (ILA-H5214) is expressed from human 293 cells (HEK293). It contains AA Ser 113 - Ala 271 (Accession # P01583-1).

Predicted N-terminus: Ser 113

Human IL-1 alpha Protein, premium grade (ILA-H5214), designed for preclinical stage, has the same activity and performance with GMP Human IL-1 alpha Protein, which enables a seamless transition from preclinical development to clinical phases. Premium Grade product offer a cost efficient alternative of GMP Grade products for the early development phase when safety of raw materials is not top priority. By using Premium Grade products in early development phase, you can transition easily into clinical and commercial phase without need to revalidate the raw materials and modify manufacturing process.

背景(Background)

Interleukin-1 alpha (IL1a) is also known as IL-1A, IL1, IL1-ALPHA,IL1F1,and is a cytokine of the interleukin-1 family. IL1a possesses a wide spectrum of metabolic, physiological, haematopoietic activities, and plays one of the central roles in the regulation of the immune responses. It binds to the interleukin-1 receptor. IL-1α is constitutively produced by epithelial cells. It is found in substantial amounts in normal human epidermis and is distributed in a 1:1 ratio between living epidermal cells and stratum corneum.The constitutive production of large amounts of IL-1α precursor by healthy epidermal keratinocytes interfere with the important role of IL-1α in immune responses, assuming skin as a barrier, which prevents the entry of pathogenic microorganisms into the body. In vitro, IL-1α possesses biological effect on cells in the picomolar to femtomolar range. In vivo, Shortly after an onset of an infection into organism, IL-1α activates a set of immune system response processes.
