PD-L1 Cell Stain Kit
At 1/10 antibody size, this kit provides deep tissue penetration and ultra-low noise. It precisely targets antigens via a rapid workflow, making it the premier choice for IF and Flow Cytometry.
This PD-L1 Genimer™ cell staining kit is a high-end immunostaining tool developed by Chipone Biotech for the immuno-oncology market. PD-L1 is a key indicator of tumors evading immune surveillance, and its accurate detection is crucial for drug development and diagnosis. This kit utilizes proprietary Genimer™ nucleic acid aptamer technology to replace traditional antibodies, providing a more penetrating and stable staining solution for PD-L1.
Because Genimer™ has a molecular weight only one-tenth that of traditional antibodies, it can penetrate dense cellular tissues more easily and accurately label target antigen sites on the cell membrane. This kit uses fluorescent direct labeling technology, which simplifies the staining process and effectively reduces background noise caused by nonspecific adsorption. It also solves the common problems of batch instability and cold chain dependence of antibodies, making it a high-quality choice for immunofluorescence (IF) and flow cytometry.
Five core features of the product:
🎯 Excellent tissue penetration: With a very small molecular weight (only 1/10 of that of antibodies), it can penetrate cell layers and dense tissues more quickly and deeply, providing a more uniform staining effect.
🚫 Extremely low background fluorescence interference: It combines high specificity and low non-specificity, significantly improving the signal-to-noise ratio and making the performance of PD-L1 clearer and more accurate.
🌡️ Excellent thermal stability: With a nucleic acid aptamer structure, it has excellent chemical stability and can maintain activity over a wide temperature range, simplifying storage and transportation processes.
🧬 0% batch variation: Fully chemically synthesized, completely eliminating the batch efficacy fluctuations common in biologically derived antibodies, ensuring a high degree of reproducibility of quantitative analysis results.
⚡ Quick and simple operating procedure: Optimized staining formula can shorten incubation time and eliminate concerns about the immunogenic interference that traditional antibodies may cause, greatly improving experimental efficiency.
