锌是必需的微量元素之一，在胰岛素和卟啉代谢中也起重要作用。本试剂盒适用于检测血清、血浆、尿液、乳汁中的锌含量。
本试剂盒检测原理如下：在特定的酸碱度条件下，锌离子与5-Br-PADAP 能形成稳定的、具有特征颜色的络合物，颜色的深浅与锌离子浓度成正比。

y：标准品OD 值；
x：标准品的浓度；
a：标曲的斜率；
b：标曲的截距；
A：样本OD 值；
2*：样本前处理时的稀释倍数；
f：样本加入检测体系前的稀释倍数

Zinc is one of the essential trace elements and plays an important role in insulin and porphyrin metabolism. This kit is suitable for detecting zinc levels in serum, plasma, urine, and milk.
The detection principle of this kit is as follows: under specific pH conditions, zinc ions form a stable, colorimetric complex with 5-Br-PADAP, the intensity of which is directly proportional to the concentration of zinc ions.

Instructions for Use
1. Preparation of Sample Supernatant
Mix the sample with protein precipitation in a 1:1 ratio, centrifuge at 4°C and 13,780 × g for 10 minutes, then collect the supernatant for testing.
Note: The supernatant after centrifugation must be clear. If turbidity is present, transfer the turbid supernatant to a new centrifuge tube and centrifuge again..
2. Preparation of standards
Using deionized water, dilute the standards (1.54 mmol/L) to 0, 1.54, 7.7, 15.4, 23.1, 30.8, 38.5, and 46.2 μmol/L according to the table below.
Serial Number | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
Concentration (μmol/L) | 0 | 1.54 | 7.7 | 15.4 | 23.1 | 30.8 | 38.5 | 46.2 |
Standard solution (μL) | 0 | 1 | 5 | 10 | 15 | 20 | 25 | 30 |
Deionized water (μL) | 1000 | 999 | 995 | 990 | 985 | 980 | 975 | 970 |
3. Preparation of Chromogenic Working Solution
Mix Chromogenic Agent and Buffer Solution at a volume ratio of 1:200. Prepare immediately before use.
4. Sample Measurement
The detection system was prepared in 1.5 mL EP tubes as per the table below.
Reagent name | Standard tube | Sample tube |
Sample (μL) | - | 200 |
Standard solutions of different concentrations (μL) | 200 | - |
Chromogenic Working Solution (μL) | 800 | 800 |
Mix well, incubate for 5 min, zero the instrument using a standard tube with a concentration of 0 μmol/L, then measure the OD value at 560 nm using a spectrophotometer. |
5. Result calculation
Standard curve equation: y = ax + b
Zinc Content Calculation: Zinc content (μmol/L) = (A - b) / a × 2* × f
y: standard OD value;
x: standard concentration;
a: slope of the standard curve;
b: intercept of the standard curve;
A: sample OD value;
2*: dilution factor during sample pretreatment;
f: dilution factor applied to the sample prior to addition into the assay system.
Precautions
1. The sample must not cause hemolysis; metal chelating agents such as EDTA and citrate cannot be used as anticoagulants.
2. The used containers and reagents should be free from zinc ion contamination.
3. Before the formal test, it is recommended to select 2-3 samples with significant expected differences for a preliminary experiment.
4. For your safety and health, please wear a lab coat and disposable gloves during the operation.
