Introduction

JJF 1071-2010 "Rules for Compilation of National Metrology Calibration Standards", JJF 1001-2011 "General Metrology Terminology and "Definition" and JJF 1059:1-2012 "Assessment and Expression of Measurement Uncertainty" jointly constitute the support for the formulation of this specification The basic series of specifications: This specification is published for the first time: Calibration specification for dot enzyme immunoassay analyzer

1 Scope

This specification is applicable to the calibration of the dot enzyme-linked immunosorbent analyzer, and the calibration of other plate types (48-well plate or 24-well plate, etc:) The spot enzyme-linked immunosorbent analyzer can be calibrated according to this specification:

2 References

This specification references the following documents: ANSI/SLAS4-2004 Microwell reaction plate: Well position (Microplates-WelPositions) For dated references, only the dated version applies to this specification; for undated references document, its latest version (including all amendments) applies to this specification:

3 terms

By coating antibodies on special microwell reaction plates, cells secreting specific cytokines are captured, and then enzyme-linked technology It is an analytical instrument that automatically microscopically counts the colored spots to form tiny spots corresponding to the cells:

4 Overview

The dot enzyme-linked immunosorbent analyzer (hereinafter referred to as the analyzer) is mainly composed of an imaging system, a motion system, and a control processing system: system and display system: During the analysis, the imaging system acquires the spot images in the wells on the microwell reaction plate, and then displays the The system performs spot statistics to obtain the total number of spots in the hole:

5 Metrological characteristics

The metering characteristics and metering characteristic indicators of the analyzer are shown in Table 1: Table 1 Quantitative characteristics of dot enzyme-linked immunosorbent analyzer Measuring characteristics Measuring characteristic indicators Spot count indication error ±5:0% Repeatability≤2:0% Note: The above technical indicators are not applicable to qualification judgment and are for reference only:
