Product Details
Background
IL-7 (Interleukin-7) is a cytokine that plays important roles in lymphocyte differentiation, proliferation, and survival. IL-7 is produced by stromal epithelial cells of the thymus, bone marrow, and intestines. It signals through a receptor complex composed of IL-7 R alpha/CD127 and the Common gamma Chain. gamma c is also a subunit of the receptors for IL-2, -4, -9, -15, and -21. IL-7 contributes to the maintenance of all naïve and memory T cells. It is required for optimal T cell-dendral cell interaction. In mouse, IL-7 activation of IL-7 R alpha is critical for both T cell and B cell lineage development, while in humans, it is required for T cell but not for B cell development.

Intra-assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-assay Precision (Precision between assays) Three samples of known concentration were tested six times on one plate to assess intra-assay precision.
Spike Recovery
The spike recovery was evaluated by spiking 3 levels of human IL-7 into health human serum sample. The un-spiked serum was used as blank in this experiment.
The recovery ranged from 80% to 96% with an overall mean recovery of 88%.

Serum/Plasma – Thirty samples from apparently healthy volunteers were evaluated for the presence of IL-8 in this assay. No medical histories were available for the donors.
