With extensive experience in aptamer development, our scientists are confident in providing a full range of aptamer screening services to advance science and technology development. Creative Biolabs is able to provide aptamer screening services in an efficient and high-quality manner.

SELEX technology can be used to obtain aptamers with specific binding ability to the target. Aptamers have been shown to partially replace antibodies in research and clinical applications, and are a promising technology area.

Fig 1. Schematic diagram of the SELEX process ^[1].

The key to the development of aptamer technology is the screening of aptamers with high affinity and specificity for the target. Over the past decade, the aptamer screening technology has been improved to improve the efficiency and effectiveness of screening, and new methods such as ablation screening, compound target screening, genomic screening, capillary screening, etc. have been generated to promote the development of this technology.

Advantages of Aptamer

• Short cycle time and high affinity and specificity of aptamer assays compared to monoclonal antibodies.
• Compared to antibody assays, the aptamers obtained from screening are easy to synthesize in large quantities in vitro, reproducible, stable and easy to store.
• Aptamer screening is simple and easy to perform, and the cost of the assay is low.
• A wide range of aptamer targets, including pesticides, tissues, cells, viruses, proteins, toxins, vitamins and allergens.
• Aptamers are easily labeled with fluorescence and their activity is not affected, so they can be easily combined with other assay technologies.

Applications of Aptamer

Similar to monoclonal antibodies, aptamers can specifically recognize and bind to their targets. Due to their simple preparation, ease of modification and stability, aptamers have been used in various fields of molecular biology, biotechnology and biomedicine.
