LymphoprepTM分離液
工作原理
PBMC與血液中的其他成分存在密度差異,利用密度在1.077±0.001g/ml之間而且近于等滲的LymphoprepTM溶液作密度梯度離心時(shí),紅細(xì)胞和粒細(xì)胞由于密度大,故沉于分離液底部。PBMC密度稍低于分離液,故位于分離液界面上,獲得PBMC。LymphoprepTM分離液含有多糖(polysacccharide),多糖能粘附在細(xì)胞表面,使紅細(xì)胞和粒細(xì)胞聚集下沉,但它對(duì)淋巴細(xì)胞的活性和紅細(xì)胞和粒細(xì)胞進(jìn)一步分離有負(fù)面影響。
注意事項(xiàng):
1、該分離液僅適用于人體的外周血液,不適用于動(dòng)物。
2、使用該分離液時(shí),需將待分離的血液用生理鹽水做等體積的稀釋。
3、分離液的保存應(yīng)置于無菌環(huán)境,并避光保存。
4、詳細(xì)操作步驟見產(chǎn)品說明書。

Meet the new optical measurement system for absolute irradiance measurements of solar simulators and other radiant sources. The new RaySphere from Ocean Optics measures absolute irradiance over spectral ranges from the UV to the NIR (350 to 1700 nm).
This portable system is ideal for solar simulator manufacturers and research and development labs as a tool to validate the output of installed solar flashlamps. The flash of a solar simulator is used within the photovoltaic (PV) manufacturing process for the binning of cells according to spectral response and for final PV module efficiency measurements.The RaySphere system delivers the accuracy and resolution needed to measure and analyze the performance and stability of the flasher with ultralow jitter triggering electronics for timing the measurement to the flashes. Calibration has been validated by an accredited certification lab to ensure accurate detection, enabling evaluation and qualification of the spectral distribution of solar flashers and simulators according to the IEC60904-9 (2007) standard.The system includes two thermoelectrically cooled detectors that perform repeatable and accurate spectral analysis of solar flashers from 350 to 1700 nm, and a second version contains a single cooled detector for measurement to 1100 nm.
RaySphere includes high-speed electronics and an intuitive powerful software interface. Brief measurement times enable detection of a complete spectrum during a flash or even during a portion of the flash. The measurement can be triggered by a fast response photodiode that reacts on the increasing intensity of the flashlight with sub-microsecond response times.
