Fluorescent dyes are indispensable tools in the field of biomedical research. A deep understanding of their fundamental principles is crucial for the flexible use of this tool. By leveraging the fluorescence properties of dyes, researchers can selectively observe specific organelles or proteins from complex biological systems. For example, fluorescent dyes can be used to visually observe mitochondrial structures in living cells with extremely high sensitivity and selectivity.

In the field of life sciences and drug development, precise labeling of proteins and antibodies is a critical step in obtaining reliable data. Protein/antibody labeling refers to the process where labeling substances are covalently bound to specific groups on the target protein or antibody, allowing for qualitative, positional, and quantitative analysis using the properties of the labels. HanCheng Bio possesses a rich reserve of labeling technologies and an experienced professional team, capable of providing you with efficient, stable, and highly customized labeling services. We focus on creating personalized solutions tailored to meet diverse customization needs in one stop.

Our strengths

Diversified marking technology

We offer a variety of labeling techniques, including fluorescence labeling (such as FITC, Cy series, Alexa Fluor), biotin labeling, enzyme labeling (such as HRP, AP), isotope labeling, and chemiluminescent labeling. These techniques can meet the needs of various experiments, such as immunofluorescence (IF), flow cytometry (FACS), ELISA, Western Blot, and in vivo imaging.

Precision and high sensitivity

We use the directed labeling process to maximize the retention of protein/antibody activity and effectively avoid non-specific binding. The purity of the labeled product is over 95%, and the signal intensity is increased by 30%-50%, ensuring that the experimental results have high repeatability and low background interference.

Customized services throughout the process

From marker strategy design, marker condition optimization to product purification and quality control (such as SDS-PAGE), we provide customized solutions according to your experimental requirements to effectively address the challenges posed by rare samples, special modifications or complex application scenarios.

Fast delivery, safe and reliable

Standard projects can be completed within 3-7 working days, and urgent needs can be provided with expedited processing services. We strictly follow the ISO quality management system to ensure data confidentiality and sample security.
