CY80SI-AH+TB试剂选型与应用维护指南

CY80SI-AH+TB Reagent Overview

CY80SI-AH+TB reagent is a dedicated reagent used with E+H online analyzers, widely applied in water quality online monitoring scenarios such as COD, ammonia nitrogen, and total phosphorus. Correct selection and standardized maintenance directly affect the measurement accuracy and operational stability of the analyzer.

This article focuses on reagent configuration and selection, application scenarios, preparation steps, and maintenance precautions, providing practical reference for engineering technicians and procurement personnel.

Reagent Configuration Selection and Application Scenarios

Antibody Combination Selection

CY80SI-AH+TB reagent is usually used in combination with specific antibodies for detecting antigens on the cell surface or in the cytoplasm. Depending on the experimental purpose and the antigen to be detected, different antibody combinations can be selected to achieve the best staining effect.

Diluent Selection

To reduce background staining and improve specific staining, it is usually necessary to select an appropriate diluent to dilute the reagent. Common diluents include:

Phosphate-buffered saline (PBS)
Normal saline

An appropriate diluent should be selected according to experimental requirements to ensure the best staining effect.

Staining Temperature and Time

Staining temperature and time are key factors affecting the staining effect. Staining at room temperature is usually sufficient, but the temperature can also be adjusted as needed. Staining time is generally controlled at 30 minutes to 1 hour, depending on the antigen properties and antibody concentration.

Washing Steps

Washing can remove unbound dye and antibodies and improve the specific staining effect. During washing, gently tap or shake to avoid cell detachment.

Reagent Preparation Steps

Prepare the reagent directly before use. When ordering multiple different reagent kits, they must be stored separately to avoid mixing.

Preliminary Preparation

Prepare Component 1, Reagent RB (brown reagent bottle) and Component 2, Reagent RN.

Preparation Procedure

Open the brown reagent bottle.
Use a powder funnel to completely pour Component 2 into the brown reagent bottle containing Component 1.
Cover and seal the bottle cap.
Shake the reagent bottle for several minutes to ensure thorough mixing.

Required Materials and Tools

1 powder funnel
Water sample reagent label (1000 ml bottle)
Water sample reagent RB, water sample reagent RK (1000 ml bottle)
Component 1, Reagent RN (1000 ml bottle)
Component 2, Reagent RN (100 ml bottle)
1 printed copy of "Special Documentation"

Precautions and Maintenance

Safety Protection

Chemicals not only irritate the skin and eyes but may also cause serious injury or death. When handling chemicals, safety goggles and protective gloves must be worn, and a lab coat should be worn to avoid direct contact with chemicals. Operations should strictly follow the detailed instructions in the chemical safety data sheet.

Storage Conditions

Reagents should be stored in a 4°C refrigerated environment, avoiding repeated freezing and thawing. Before use, the reagent should be brought to room temperature and shaken thoroughly.

Avoid Light Exposure

The reagent contains fluorescent dyes. Prolonged exposure to strong light may cause the dye to decompose and affect the staining effect. During operation, avoid direct light exposure and conduct experiments under low-light conditions as much as possible.

Prevent Cross-Contamination

During use, ensure the independence of each experimental sample, stain only one sample at a time, and avoid contact with other samples.

Quality Control

To ensure the accuracy of experimental results, it is recommended to perform quality control tests before use. You may refer to the quality control standards provided by the reagent manufacturer or set your own quality control standards.

Waste Disposal

Used reagents and waste liquids should be disposed of in accordance with laboratory waste disposal regulations to avoid harm to the environment and personnel.

Training and Safety

Operators should receive relevant training and understand the safety and precautions of the reagent. Follow laboratory safety regulations and wear appropriate protective goggles, lab coats, and gloves. If skin or eye contact occurs accidentally, immediately rinse with plenty of water and seek medical attention promptly.

Validity Period and Shelf Life

Checking the shelf life and validity period of the reagent is crucial to ensuring experimental quality. Ensure the reagent is used within its validity period and follow the storage conditions and usage instructions provided by the manufacturer.

Warranty Period Reference
