产品概述

恶喹酸检测试剂盒酶联免疫反应测试盒基于竞争性酶联反应原理,含有恶喹酸检测试剂盒(SEM)的抗体已经包被于微孔板上。药物分析时,样品同SEM-HRP共同被添加到板孔中。如果样品中含有SEM,会竞争SEM抗体,抑制SEM-HRP与板上包被的抗体结合。加入底物后,产物的颜色强弱与样品中SEM的浓度成反比。

注意事项

实验前请阅读以下文字,以保证获得*佳实验效果。

1)      标准品中含有恶喹酸检测试剂盒,请小心使用。

2)      不要使用过期的试剂盒。

3)      不同批次的试剂盒不要混用,抗体和微孔板具有盒与批次的特异性。

4)      尽量保持室温20-25℃,避免在通风口操作防止温度过低,过热和/或者蒸发。同样的,不要在阳光直射下实验,防止过热及蒸发。在孵育期间,如果工作台温度过低,应该铺垫若干纸巾或者其他物料。

5)      水质量很重要,确保使用蒸馏或者去离子水。

6)      加入样品或者试剂到空的微孔板时,吸嘴靠于微孔接近底部,并保持接触。

7)      孵育时间的计算越规范越好,保持添加标准品的一致性,先添加标准品后添加样品。

8)      从低浓度到高浓度地添加标准品,降低影响标准品曲线质量的风险。

9)      将微孔板置于放有干燥剂的密封袋中,冷藏保存。

样品的准备恶喹酸检测试剂盒

确保样品的正确保存,一般来说,样品在2-4只能保存1-2天,如果要保存更长时间,就要保存在-20冷冻保存,在用之前需要将冷冻的样品在室温下或冰箱内解冻。

10.结果计算恶喹酸检测试剂盒

(1)    分别计算标准、质控和样品的平均吸光度值和相对吸光度值。

相对吸光度值 (%) = (标准或样品吸光度值/零标准吸光度值) ´ 100

(2)    以相对吸光度值为纵坐标,标准浓度为横坐标建立标准曲线。

(3)    从标准曲线上读取质控和样品的浓度值。

(4)    样品检测下限计算方法如下:

样品检测下限 = (0.025ng/g) ´ (稀释倍数)

样品定量下限 = (0.1ng/g) ´ (稀释倍数)

例如,肉类样品的稀释倍数是2.0,那么肉类样品的检测下限是0.05ppb,定量检测下限是0.2ppb

9243654  Comprehen Valid., Other Quant. Sys.      """The Comprehensive Validation Support plan specific to a laboratory's needs will incorporate all of the requirements for the internal validation guidelines from the FBI's Quality Assurance Standards (QAS).

 

The Comprehensive Validation Support service includes all travel and labor charges for up to 20 days by the QIAGEN Validation Team. Typically, one week will be required to extract, quantify, and amplify the validation study samples and may require multiple individuals. Usually, two weeks is required to analyze the data and one week to write the final report. The expected time period to complete the Comprehensive Validation is six weeks. The actual time may vary depending on resource availability, including laboratory time dedicated to validation activities.

 

Lab Work – The QIAGEN specialist(s) will travel to the laboratory to conduct the on-site validation lab work. The QIAGEN specialist team will perform and complete all extractions, quantifications, amplfications, and capillary electrophoresis. The laboratory is responsible for providing systems/protocols that may be needed (generally laboratory SOPs, ex. interpretation guidelines). Additionally, the laboratory staff may be required to provide additional data needed for interpretation (ex. quantification/amplification/CE results) during the data review phase of the validation.

 

Once the final scope of the validation is determined, QIAGEN will provide a quote for all consumables required for the validation.  Non-QIAGEN chemistry and accessories are not included and should  be purchased to cover the validation experimental design including qPCR, STR, NIST standards, required samples types (blood, semen, buccal samples) and required substrates (swabs, materials, etc).   For planning purposes and to ensure a smooth process, the Customer is expected to have all materials on-hand and inventoried one (1) week prior to the validation start date.

 

Data Analysis – The Comprehensive Validation Support plan encompasses data collection (quants, amps, CE) during the on-site visit. The laboratory may be responsible for sharing (typically electronically via e-mail) any validation data requested after the on-site visit. A QIAGEN specialist will complete all of the data analysis produced from the validation study design. This includes qPCR (quant) and STR (amp) analysis and linkage to starting samples.

 

Validation data CD/flashdrive – QIAGEN will review the validation data and draft a validation summary document, ensuring compliance with the FBI's QAS requirements/standards. QIAGEN will send validation data in an electronic format (email/CD/flashdrive) to the laboratory. The laboratory is responsible for final compilation, any format change preferences, review and signoff of the validation report. The documentation provided by QIAGEN will aide in demonstrating compliance with all accreditation guidelines during laboratory audits. Should a hard copy of the validation study be preferred, the laboratory is required to specify prior to the onset of the validation.

 

Post-validation QIAGEN-to-Laboratory Transfer – Following completion of the validation and generation of the draft validation summary document, a designated member of the QIAGEN validation team will review the validation with the Lab Manager and the Technical Leader. Following sign off on the validation report, training of the laboratory DNA staff will occur. Refer to the Post-validation Competency Training for additional information.
