Sartorius CN140NC membrane nitrocellulose membrane
information:
It is used as the carrier of the C/T line in colloidal gold test paper, and is also where immune reactions occur. NC membrane is raw
One of the most important consumables in physical experiments.
Introduction to use:
*, the pore size of the nitrocellulose membrane (chromatography speed), as well as the processes and configurations between different manufacturers
The variance difference has a significant impact on the colloidal gold test paper. The more commonly used chromatography speed is 140s/4cm. On this basis, it can
Choose a faster or slower chromatography speed based on the sensitivity requirements of the product and then choose that chromatography between different manufacturers
The speed of the membrane was further tested for comparison.
Material characteristics:
Uniform thickness, high liquid climbing speed, and high surface quality.
Sartorius CN140NC membrane nitrocellulose membrane product introduction:
Sartorius uses individually sterile packaged nitrocellulose mesh membranes as filters for microbial detection.
· Nitrocellulose material is suitable for microbial growth, with a microbial recovery rate >90%;
· There are grid lines on the membrane, which facilitates counting and does not affect the growth of bacterial colonies;
· Diaphragms with bacterial colonies can be stored as test records* after drying, complying with GMP requirements.
Detailed introduction of Sartorius Sartobind microporous ion exchange membrane
In the process of protein separation and purification, ion exchange column chromatography is one of the commonly used methods. However, due to some defects of ion exchange column chromatography itself, its actual application process is complicated and time-consuming. For small sample processing, the flow rate can only be limited to the range of 1-10ml/min. If the flow rate is too high, it will cause resin damage. It has shortcomings such as easy damage, and ion exchange column chromatography can only be used in the protein separation process, but cannot concentrate the protein.
In order to solve this problem, the German company Sartorius specially invented a new technological concept product called microporous ion exchange membrane (SartobindTM). This product has very high practical value. It can be used with a preparative liquid chromatograph or a fast peristaltic pump. A syringe can also be used to process a small amount of samples. The protein can be purified and highly concentrated in one experiment. The work is completed at the same time. The microporous ion exchange membrane has the characteristics of strong pressure resistance, high chemical stability, large adsorbed protein capacity (2mg/cm2), fast flow rate (up to 3L/min), short running time, simple and convenient operation, etc. . All operations using this method to process and prepare proteins, whether in grams or kilograms, are very simple.
