【人CD160分子(CD160)ELISA試劑盒】ELISA 樣本的處理

ELISA 檢測(cè)的目的是為實(shí)驗(yàn)提供準(zhǔn)確可靠的定量分析實(shí)驗(yàn)依據(jù)。為了保證實(shí)驗(yàn)數(shù)據(jù)的可靠性，在實(shí)驗(yàn)過(guò)程中必須堅(jiān)持全面質(zhì)量控制和全過(guò)程質(zhì)量控制。在收集標(biāo)本前都必須有一個(gè)完整的計(jì)劃。齊一生物銷售：021－6034 8496；181214 53965；173021 04490

注意事項(xiàng)：

◆ 每個(gè)標(biāo)本量收集體積＝ 100ul × 檢測(cè)種類，如要做復(fù)孔，標(biāo)本量收集體積＝ 100ul × 檢測(cè)種類×2 。

◆ 對(duì)于作某一個(gè)具體指標(biāo)來(lái)說(shuō)，先用一系列稀釋度作一批標(biāo)本測(cè)定，得出對(duì)實(shí)驗(yàn)有意義的一個(gè)稀釋度（即測(cè)定劑量反應(yīng)曲線），然后用一個(gè)*適稀釋度測(cè)定即可。

◆ 收集標(biāo)本前必須清楚要檢測(cè)的成份是否足夠穩(wěn)定。對(duì)收集后當(dāng)天進(jìn)行檢測(cè)的標(biāo)本，儲(chǔ)存在4℃?zhèn)溆�，如有特殊原因需要周期收集�?biāo)本，將標(biāo)本及時(shí)分裝后放在-20℃ 或-70℃ 條件下保存。避免反復(fù)凍融。標(biāo)本 2 -8 ℃ 可保存48 小時(shí).-20℃ 可保存1個(gè)月。 -70 度可保存6個(gè)月。部分激素類標(biāo)本需添加抑肽酶。

◆ 血清標(biāo)本采集時(shí)，應(yīng)注意避免溶血，紅細(xì)胞溶解時(shí)會(huì)釋放出具有過(guò)氧化物酶活性的物質(zhì)，以 HRP為標(biāo)記的 ELISA 測(cè)定中，溶血標(biāo)本可能會(huì)增加非特異性顯色。

【人CD160分子(CD160)ELISA試劑盒】◆ 為了保證尿液檢測(cè)結(jié)果的準(zhǔn)確性，必須正確收集尿液標(biāo)本和保存。盛尿容器要清潔干燥。使用一次性的容器（如塑料尿杯），避免因用藥并清洗不干凈而造成的污染，影響檢測(cè)結(jié)果。尿液標(biāo)本必須新鮮，留取后，應(yīng)及時(shí)檢測(cè)或保存，以免細(xì)菌繁殖。因在室溫中久置后（尤其是夏季）尿中磷酸鹽等可析出結(jié)晶而干擾檢測(cè)。

◆ 標(biāo)本宜在新鮮時(shí)檢測(cè)。如有細(xì)菌污染，菌體中可能含有內(nèi)源性 HRP，也會(huì)產(chǎn)生假陽(yáng)性反應(yīng)。保存過(guò)久可發(fā)生聚合在 ELISA中可使本底加深。

◆ 凍結(jié)標(biāo)本融解后，蛋白質(zhì)局部濃縮，分布不均，應(yīng)充分混勻宜輕緩，避免氣泡，可上下顛倒混和，不要在混勻器上強(qiáng)烈振蕩。

◆ 混濁或有沉淀的標(biāo)本應(yīng)先離心或過(guò)濾，澄清后再檢測(cè)。

◆ 反復(fù)凍融會(huì)使蛋白效價(jià)降低，所以待測(cè)標(biāo)本如需保存作多次檢測(cè)，宜少量分裝冰存。也可加入適當(dāng)防腐劑。

◆ 如果您在實(shí)驗(yàn)中遇到任何特殊問(wèn)題，敬請(qǐng)咨詢 021-60348496標(biāo)本類型

ELISA常見(jiàn)的標(biāo)本一般包括：

9243652Comprehen Valid., QuantiPlex/QP Hyres"""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. """CNY
