Are the electrophoresis bands blurry? It can be improved by changing the type of suction head

Publish Time: 2025-09-22     Origin: Site

Question: I recently ran a gel electrophoresis, and the spotting process was so annoying! The sample points were always inaccurate, liquid always hung on the tip of the tip and flowed out of the well, and cross-contamination occasionally occurred. Problems occurred repeatedly in the experiment, and the efficiency was extremely low.


Answer: It is indeed easy to encounter these situations during electrophoresis spotting, which can affect the progress. By the way, our Aijin Biogel Spotting Tips are specially designed to meet the spotting needs of electrophoresis experiments.


Question: Oh? So, can it help solve problems such as inaccurate points, fluid leakage, and contamination?


Answer: This tip is specially adapted to electrophoresis experiments. The design has been optimized to help the sample enter the spotting hole more accurately, and can also reduce the amount of liquid hanging on the tip, which has a positive effect on reducing the risk of cross-contamination.


Answer: Regarding its specific situation, the following are the details of our gel spotting tip for your reference.




Core uses of gel dispensing tips



Different from conventional pipetting tips, the design of #gel dispensing tips focuses on 'precise positioning and stable loading'. Its slender structure can stably feed tens to hundreds of microliters of sample into the gel's sampling hole, effectively reducing sample loss and diffusion. It is especially suitable for use in the following types of experiments:


A  Nucleic acid electrophoresis (PCR products, plasmids)

The sample volume needs to be accurately controlled (to avoid overflow in the well), and aerosol contamination must be prevented (otherwise there will be false positives).

BQuantitative  electrophoresis (such as grayscale analysis)

The requirements for sample addition repeatability are high, and the volume accuracy of the tip directly affects the quantitative results.

Protein C  electrophoresis (SDS-PAGE, Western Blot)

The sample concentration is low, the volume is small (usually 10-20 μL), and the low adsorption design can reduce protein loss and ensure clear bands.




Product advantages of gel dispensing tips



The tip of an ordinary tip is thick and blunt, and it is easy to scratch the gel hole wall and cause the sample to spread. The Aijin Biogel Spotting Tip adopts an extra-long thin tube design. The front end is extremely thin and smooth, and can easily extend into the 1.0-1.5mm gel hole (whether it is agarose or PAGE gel). The tip has a smooth cut surface and will not hang or rub off the gel in the hole. Specifically, it has the following advantages:


A  Accurate spotting

The slender tip is easy to insert into the sample hole and accurately controls the sample location.

B  avoid spreading

The fine tip design reduces sample diffusion in the well.

C  to prevent glue wear

Rounded ends avoid puncturing the bottom of the gel.

D  clear observation

The transparent material makes it easy to observe the liquid filling status.




Quality and production assurance



Aijin biogel dispensing tips are made of medical-grade polymer materials. During the production process, the concept of 'stable and reliable' is always implemented to meet:


A  ultra-clean production

No DNase/RNase contamination, no pyrogen.

BPrecision  molding

The inner wall is smooth to reduce sample residue.

C  seal performance is stable

It has strong compatibility with mainstream pipettes on the market and can provide strong guarantee for pipetting accuracy.

D  Sterilization

Gamma ray sterilization, sterility degree 10^-6




product specifications



In order to meet the needs of different experimental scenarios, #爱jinbiogel spotting tips can provide a variety of options:


A  capacity

160/200μL (meet most gel spotting needs).

Type  B

Filter element/non-filter element optional (filter element type effectively prevents aerosol pollution).

C  packaging

Boxed (96 pieces per box, easy to access and manage).

D  Sterilization

Sterile/non-sterile optional (sterilized products are sterilized by gamma rays and suitable for sensitive experiments).



In gel electrophoresis experiments, although the spotting step is small, it plays a decisive role in the experimental results. Aijin Biotechnology has always paid attention to the operating experience of scientific researchers, and hopes that through products such as gel dispensing tips, it can provide experiments with choices that are closer to the needs, stable and reliable consumables, and help scientific research work to be more efficient and smooth!
