Validation Data Gallery

• 

  Purity of recombinant human IL-1 alpha was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue.

• 

  Recombinant human IL-1 alpha (Cat no: HZ-1320) stimulates does-dependent proliferation of the D10.G4.1 mouse helper t lymphocyte cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. D10.G4.1 cells were treated with increasing concentrations of recombinant IL-1 alpha for 72 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 0.125-1.25 ng/mL.

• 

  Recombinant human IL-1 alpha (Cat no: HZ-1320) stimulates dose-dependent induction of alkaline phosphatase production in a HEK293 reporter cell line. Alkaline phosphatase production was assessed using pNPP as a chromogenic substrate. The EC50 was determined using a 4- parameter non-linear regression model. The EC50 values range from 8-40 ng/mL ng/mL EC50.

Background

IL-1 alpha is a dual function cytokine that can function both as a transcription factor and a damage-associated molecular pattern (DAMP) in innate immune responses. It is expressed by many cell types and its expression is increased when cells are exposed to growth factors, pro-inflammatory, and stress-related signals. In its pro-form, IL-1 alpha contains a nuclear localization signal that allows it to translocate to the nucleus and bind to DNA, resulting in either the increase or prohibition of pro-inflammatory cytokine expression. When cells are exposed to necrotic signals, mature IL-1 alpha is released from the cell lysates and triggers a strong pro-inflammatory response upon binding to its receptor on nearby cells. Due to its strongly pro-inflammatory nature, IL-1 alpha has been linked to tumor metastasis and lower median survival in several cancers (PMID: 27434011, 29247995).
