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 CXCL5/ENA-78 into health human serum sample. The un-spiked serum was used as blank in this experiment.
The recovery ranged from 80% to 106% with an overall mean recovery of 89%.

Serum/Plasma – Thirty samples from apparently healthy volunteers were evaluated for the presence of CXCL5/ENA-78 in this assay. No medical histories were available for the donors.
Product Data Sheet
Background: CXCL5/ENA-78
该基因编码的蛋白质是趋化因子（C-X-C基序）配体5（CXCL5），是一种属于CXC趋化因子家族的小型细胞因子，也被称为上皮细胞来源的中性粒细胞激活肽78（ENA-78）。该趋化因子与白介素-8（IL8）同时产生，响应白介素-1（IL1）或肿瘤坏死因子α（TNFA）的刺激。观察到，CXCL5也表达于嗜酸性粒细胞中，并能与II型干扰素IFN-α相互作用，从而引起抑制作用。这种趋化因子刺激中性粒细胞的趋化性，具有血管生成特性，并通过与细胞表面趋化因子受体CXCR2相互作用来引发这些效应。
