Specificity of the ELISA Kit for Erythropoietin (EPO)
This assay has high sensitivity and excellent specificity for detection of Erythropoietin (EPO).No significant cross-reactivity or interference between Erythropoietin (EPO) and analogues was observed.
Recovery of the ELISA Kit for Erythropoietin (EPO)
Matrices listed below were spiked with certain level of recombinant Erythropoietin (EPO) and the recovery rates were calculated by comparing the measured value to the expected amount of Erythropoietin (EPO) in samples.
| Matrix | Recovery range (%) | Average(%) |
| serum(n=5) | 95-104 | 101 |
| EDTA plasma(n=5) | 86-95 | 91 |
| heparin plasma(n=5) | 78-98 | 86 |
Precision of the ELISA Kit for Erythropoietin (EPO)
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Erythropoietin (EPO) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Erythropoietin (EPO) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: CV<10%>Inter-Assay: CV<12%>
Linearity of the ELISA Kit for Erythropoietin (EPO)
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Erythropoietin (EPO) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
| Sample | 1:2 | 1:4 | 1:8 | 1:16 |
| serum(n=5) | 87-94% | 91-101% | 84-98% | 81-101% |
| EDTA plasma(n=5) | 80-89% | 93-101% | 80-97% | 85-93% |
| heparin plasma(n=5) | 78-103% | 88-95% | 83-91% | 91-105% |
Stability of the ELISA Kit for Erythropoietin (EPO)
The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Incubate 10-20 minutes at 37°C;8. Add 50µL Stop Solution. Read at 450nm immediately.
Test principle of the ELISA Kit for Erythropoietin (EPO)
The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Erythropoietin (EPO). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Erythropoietin (EPO). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Erythropoietin (EPO), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Erythropoietin (EPO) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

移液管移液管有两种类型.一种只有一个刻度,只能量取一定体积的液体,如25mL.另一种上的刻度和滴定管类似,每小格也表示0.1mL.移液管使用时通常用吸球吸取液体。移液管是吸入溶液的，不是固定的，流出溶液是靠壁流出的；
1、移液管是准确移取一定量溶液的量器（量出式量器，符号为Ex）. 它是一根细长而中间膨大的玻璃管在管的上端有一环形标线，膨大部分标有它的容积和标定时的温度.常用的移液管有10 mL、25 mL、50 mL、100mL等规格。
2、吸量管的全称是"分度吸量管",又称为刻度移液管. 它是带有分度线的量出式玻璃量器。用于移取非固定量的溶液。吸量管可分为以下四类：
（1） 规定等待时间15s的吸量管
这类吸量管零位在上,完全流出式,它的任意一分度线的容量定义为:在20℃时，从零线排放到该分度线所流出20℃水的体积(m1).当液面降到该分度线以上几毫米时,应按紧管口停止排液15s，再将液面调到该分度线。在量取吸量管的全容量溶液时,排放过程中水流不应受到限制，液面降至流液口处静止后，要等待15s，再移走吸量管。
（2） 不完全流出式吸量管。
不完全流出式吸量管均为零点在上形式，最低分度线为标称容量.这类吸量管的任一分度线相应的容量定义为：20℃时，从零线排放到该分度线所流出的20C水的体积(mL) 。
（3）完全流出式吸量管。
这类吸量管有零点在上和零点在下两种形式.其任一分度线相应的容量定义为:在20℃时,从分度线排放到流液口时所流出20℃水的体积(mL),液体自由流下,直到确定弯月面已降到流液口静止后,再脱离容器(指零点在下式);或者从零线排放到该分度线或流液口所流出20℃水的体积(指零点在上式)。
（4） 吹出式吸量管。
这类吸量管流速较快，且不规定等待时间。有零点在上和零点在下两种形式，均为完全流出式。吹出式吸量管的任意一分度线的容量定义为：在20℃时，从该分度线排放到流液口(指零点在下)所流出的或从零线排放到该分度线(指零点在上)所流出的20℃水的体积(m1)。使用过程中液面降至流液口并静止时，应随即将最后一滴残留的溶液一次吹出。
目前市场上还有一种标“快”字的吸量管，其容量精度与吹出式吸量管相近似。吹出式及快流速吸量管的精度低、流速快，适于在仪器分析实验中加试剂用，最好不用其移取标准溶液。
吸量管的其它操作方法同移液管。
四字原则：吸 擦 调 放
吸：用吸耳球吸取液体，四指拿移液管，食指扣于移液管上口。
擦：吸取后用滤纸擦干管壁。
调：放松食指使液体流出，调至刻度线，按紧。
放：沿器壁放入所需容器。
垂直是为了保证最后只剩下半滴时，移液管不计算在内的体积。如果移液管上没有写“吹”字，那么最后半滴可以不要。
移液管
用来准确移取一定体积的溶液的量器。移液管是一种量出式仪器，只用来测量它所放出溶液的体积。它是一根中间有一膨大部分的细长玻璃管。其下端为尖嘴状，上端管颈处刻有一条标线，是所移取的准确体积的标志。
移液管,即带很多小刻度移液管
