Revealing the pollution problems and solutions during the use of acridine esters

Acridine ester, as a highly sensitive chemiluminescence marker, is prone to false positive signals due to contamination, mainly caused by improper operation or incomplete cleaning of containers. Under standardized operation, pollution can be controlled, but if pollution occurs, solvents such as DMF or DMSO should be used to fully dissolve the residue, and then thoroughly cleaned with pure water. It is recommended to use specialized containers and strictly follow the operation and cleaning procedures to ensure accurate and reliable test results. Hubei Xindesheng can provide professional acridine ester products and related technical support.

Key points and secrets to avoid salt interference when configuring Carbomer 940 gel

Key points and secrets to avoid salt interference when configuring Carbomer 940 gel

Special attention shall be paid to the configuration of Carbomer 940 gel: avoid adding soluble salts such as sodium chloride to prevent the irreversible decline of viscosity due to the destruction of gel structure; It is strictly prohibited to directly add strong acidic solutions. Other acidic components should be added after complete neutralization (pH 6-8); The impact of weak acidic substances such as hyaluronic acid and hydrosol is relatively small, but it is still recommended to test them in advance. The order of adding raw materials is crucial for system stability, and it is recommended to gradually add them in sequence. As a professional supplier, Hubei Xindesheng can provide high-quality Carbopol and related technical support.

CAPS buffer: Key raw materials for rewriting the pattern of water-based coating curing agent industry

CAPS buffer: Key raw materials for rewriting the pattern of water-based coating curing agent industry

Under the global trend of environmental protection, water-based coatings have become mainstream, but their core curing agent polyisocyanates have poor water dispersibility. CAPS (3-cyclohexylaminepropanesulfonic acid) has effectively broken through industry bottlenecks and become a key material for promoting the upgrade of water-based curing agents through mild reaction conditions, improved coating quality, and enhanced formulation flexibility. High quality CAPS is crucial for the modification effect, and Hubei Xindesheng provides high-purity products and related technical support.

Accurately measuring the pH of Tris buffer: key techniques for selecting the right pH meter and electrode

Accurately measuring the pH of Tris buffer: key techniques for selecting the right pH meter and electrode

Hubei Xindesheng Materials reminds you that the accuracy, calibration, and automatic temperature compensation function of the pH meter are decisive factors in accurately measuring the pH of Tris buffer solution. Choosing a suitable pH electrode (avoiding interference from silver chloride electrodes) and measuring under constant temperature conditions can ensure the accuracy of pH values. Meanwhile, using a pH meter with automatic temperature compensation can help overcome the issues caused by the temperature sensitivity of Tris buffer solution.

What raw materials can be used for PCR experiments? This article is enough!

The success of polymerase chain reaction (PCR) depends on the selection and quality control of key raw materials. Its core components include: template DNA (requiring high purity to avoid inhibitors), specific primers (requiring reasonable design and validation), high fidelity DNA polymerase (selecting enzymes with different characteristics according to experimental needs), high-purity dNTPs (as synthetic substrates), and a stable buffer system (maintaining pH and ionic strength, especially Mg ² ⁺ concentration is crucial for the reaction). By optimizing the combination of raw materials and experimental conditions, and setting up positive and negative controls, the specificity, efficiency, and reliability of PCR reactions can be ensured.
