In scientific research experiments, different experimental needs often require centrifuge tubes of different specifications. In order to better adapt to diverse experimental scenarios, Aijin Biotech has solemnly released a new centrifuge tube product. The new product capacity range covers 1.5ml, 2.0ml and 5ml Aijin Biotech. Zan 171 has a variety of specifications and diverse choices. 1) 5ml centrifuge tube Aijin has specially launched 5ml centrifuge tubes, which are divided into three types: snap-on type, non-clip type and screw cap type, which can be flexibly adapted to different experimental needs. The pointed bottom design facilitates the reaction and transfer of various solutions, and can also be adapted to a 15ml centrifuge tube rack, providing convenience for your experimental operations. The screw cap design has stronger sealing performance, making sample storage safer and more reliable. 2) 1.5ml/2.0ml centrifuge tubes. For experiments that require the processing of micro-volume solutions, Aijin has launched new 1.5ml and 2.0ml buckle-free centrifuge tubes, which are specially designed for the loading, reaction and transfer of micro-volume solutions to meet precise experiments.

In protein research, clear protein visualization is key. Coomassie Brilliant Blue staining is a classic and efficient solution for quickly visualizing protein bands in gels, benefiting both novice and experienced researchers. Let’s learn about this practical dyeing technique! Concept Coomassie Brilliant Blue staining is a widely used protein staining technique. It binds to the protein through brilliant blue G-250, making the protein appear blue in the gel, allowing the protein to be visualized in the gel. Classification There are two main types of Coomassie brilliant blue staining: rapid staining and traditional staining. Rapid staining can be completed in 1-2 hours but is less sensitive, traditional staining takes longer (usually overnight) but is more sensitive. Experimental Step 01 Protein Electrophoresis: First separate the protein through SDS-PAGE electrophoresis, and select the appropriate gel and electrophoresis according to the size and charge of the protein.

Protein extraction is the first step in doing a WB experiment. In order to ensure the quality and stability of the protein, it is necessary to maintain low temperature throughout the extraction process and pre-cool the centrifuge and the centrifuge tube containing the protein in advance. 1. Cell plating: Use a 6cm small dish for cell plating. The cover and bottom need to be marked. Use the '∞' method to shake the cells evenly. Samples were collected when the cell density reached 90%. It is recommended to use Aijin 6cm cell culture dish. After TC treatment, the cell adhesion effect is good. 02 Collect the sample and it is almost done. Discard the old culture medium and wash it twice with PBS (the cells are still viable cells at this time and there is no need to pre-cool the PBS). Use a pipette tip to absorb the remaining liquid and place the culture dish on ice to pre-cool. If the cells grow at different rates, the samples can be placed at -80°C first and then extracted after all samples are collected. 03 Lysis: Lyse on ice for 15 minutes. Add 120 μL of lysis solution to a 6cm dish (can be used directly without adding P Read More

Centrifuge tubes are one of the commonly used consumables in laboratories. According to different uses and specifications, they can be divided into conventional centrifuge tubes and microcentrifuge tubes. 01 Conventional centrifuge tubes for efficient processing of medium-volume samples Conventional centrifuge tubes are available in different specifications, including 5ml, 15ml, 25ml and 50ml. This type of centrifuge tube is mainly used for sample storage, centrifugal separation and precipitation, and has high chemical resistance and high temperature resistance. In order to effectively solve common problems in experiments, Aijin has upgraded its centrifuge tube products. The details are as follows: The screw cap is easy to operate with one hand. The screw cap design is more convenient for one-handed operation, greatly improving experimental efficiency. The thickened tube wall can withstand high-speed centrifugation, greatly improving safety. Marking the maximum freezing line facilitates precise control of liquid filling and avoids pipe bursting due to excess. The bottle body, which can withstand 130℃, is made of pp environmentally friendly material and is suitable for a variety of experimental environments. Black circles are added to the scale lines to make the numbers clearer and more eye-catching, making them easier to read and less likely to wear out. Mold mark Read More

Ultraviolet (UV) sterilization is a common sterilization method without chemical pollution that uses short-wavelength ultraviolet radiation (especially UVC wavelength between 200-280 nm) to prevent the reproduction and growth of microorganisms by destroying their DNA or RNA. Preparation Before performing UV sterilization, the following preparations need to be performed: Cleaning: Clean the surface or space to be sterilized to remove dust and organic matter that will protect microorganisms from the effects of UV light. Safety: Ensure that all personnel understand the procedures and hazards of ultraviolet sterilization and avoid direct exposure to UVC light, which is harmful to skin and eyes. Determine the sterilization area and select the appropriate sterilization method according to the different objects to be sterilized: Space sterilization: Confirm that the position of the ultraviolet lamp can cover the entire laboratory space. Object surface sterilization: place the object under an ultraviolet light source to ensure that the light can be directly illuminated Read More
