Instrument Stability Test (IST)

Instrument Stability Test (IST)
Shanghai RuiYu BioTech has established a comprehensive validation plan that test and monitor the stability and accuracy of the result of Countstar Mars to guarantee the data is reliable in the daily use. Shanghai RuiYu BioTech has deigned an examination program (Instrument Stability Test, IST) to make sure that performance of instruments meets the requirements of cGMP regulated environments. IST will examine and calibrate the instrument once in a period of time to prove that the result measured by this instrument remains accurate and stable after years of use.

Development of bioprocessing in antibody Production during the whole Process

During the whole process from antibody R&D to production, there are many steps need to carry out cell based assay to evaluate the process or quality control. Such as the total cell concentration and viability will define the status of the cell culture.

Trypan blue cell counting and viability

Countstar is applicable to cells with diameter of 5-180um, like mammalian cell, insect cell, and some planktons.

Cell Size Analysis

The change of cell size is a key feature and is commonly measured in cell research. Normally it will be measured in these experiments: cell transfection, drug test and cell activation assays.
