[a]https%3A%2F%2Fwww.biolink.com%2Fproducts%2Faffinity-chromatography%2F[/a] <br>#affinity #chromatography #resins <br>In the downstream separation and purification process of biopharmaceuticals, chromatography is one of the indispensable separation methods. BioLink provides customers with 5 different chromatography solutions, including gel filtration chromatography, ion exchange chromatography, affinity chromatography, hydrophobic chromatography and multimodal chromatography. In addition, BioLink also produces chromatography columns and prepacked columns from laboratory to industrial grade. We focus on providing customers with high-quality products, professional solutions and comprehensive after-sales services. <br> <br>FAQs of Affinity Chromatography <br>Q <br>What is the principle of affinity chromatography resins? <br>A <br>Affinity chromatography is a selective purification method that captures target molecules from complex systems based on highly specific biological interactions between two molecules. <br> <br>FAQ <br>Q <br>How to select the appropriate chromatography resin for my own process? <br>A <br>When using affinity chromatography for purification, we need to fully evaluate the structure and affinity site of the target product. For example, some recombinant proteins will introduce histidine tags during the carrier construction stage, and affinity packing materials containing nickel ions can be used for capture; while for recombinant proteins containing GST tags, glutathione affinity chromatography can be used. For the capture of therapeutic antibodies (monoclonal antibodies, double antibodies, and polyantibodies), it is necessary to select chromatography media based on the antibody structure. For example, for antibodies containing the complete antibody structure (including the Fc region), protein A and protein G affinity chromatography can usually be used for capture. <br> <br>FAQ <br>Q <br>How many chromatography resin can BioLink produce per year? <br>A <br>BioLink&#039;s chromatography medium production base is located in Lanzhou City, Gansu Province, covering a total area of over 7,000 square meters. With a total investment of more than 100 million yuan and nearly 100 employees, the factory is responsible for the R&amp;D and manufacturing of purification and cell culture products such as chromatography packing materials and microcarriers. Up to now, the base has a 500L and 1000L chromatography packing production line, and a well-equipped quality testing laboratory (which has passed the ISO9001:2015 quality management system certification). The planned total capacity of the plant is 80,000 liters/year. <br> <br>There are many bioprocessing companies, but we are one of the best choices for you.

This needle, which has a black color code covering, can be assembled with the more typical multi-sample needle ETS system. <br> <br>The 23g needles are used when a person’s vein is much narrower than average. It is light blue color coded. <br> <br>What Size Needle is Used for Blood Draws? <br>Unlike standard measurement systems, gauge numbers and needle size have an inverse relationship. The needle width narrows as the gauge number increases. The most widely used needles in the medical industry range from number 7, the largest, to number 33, the smallest. The most widely used needles for venipuncture are 21-gauge needles, while 16-gauge needles are commonly used for blood donation because they are thick enough to allow red blood cells to pass through the needle without being broken. <br> <br>Now the price of needle for blood extraction is reasonable, if you have needs, please contact us. <br> <br>As a medical laboratory consumables supplier, we can provide kinds of medical consumables for sale, if you are interested, please leave us a message.
