• • PROTAC Synthesis

  PROTAC Synthesis represents a rapidly advancing area in medicinal chemistry, centered on the development of a novel class of small-molecule agents—PROTACs. Unlike conventional inhibitors that act solely on the active sites of proteins, PROTACs harness the cell’s ubiquitin–proteasome system to induce the selective degradation of pathogenic proteins, thereby eliminating them at the functional level. PROTAC Synthesis involves the conjugation of two functional ligands—one that binds to the target protein and...

• • Single Cell BCR Sequencing

  Single cell BCR sequencing is a high-throughput technology that enables the analysis of B cell receptor (BCR) sequences and expression profiles at single-cell resolution. BCRs are membrane-bound immunoglobulins expressed on the surface of B cells that specifically recognize foreign antigens, initiating the humoral immune response. Upon antigen exposure, B cells are activated through BCR recognition and subsequently undergo clonal expansion, somatic hypermutation, and class switching to produce.........

• • Single Cell miRNA Sequencing

  Single cell miRNA sequencing is an advanced methodology designed to profile microRNA (miRNA) expression at the resolution of individual cells. This technique integrates single-cell isolation, high-throughput sequencing, and small RNA analysis to enable the precise delineation of heterogeneous miRNA expression patterns among distinct cell populations. miRNAs are ~22-nucleotide non-coding RNAs that are ubiquitously present in eukaryotic organisms, playing essential roles in gene regulation, cell fate ........

• • Single Cell and Spatial Transcriptomics

  Single cell and spatial transcriptomics represent groundbreaking technologies that enable the resolution of gene expression at the single-cell level while simultaneously preserving the spatial localization of cells within tissue contexts. Conventional transcriptomic analyses, which rely on bulk cell populations, often mask cellular heterogeneity and thus limit the resolution at which complex biological systems can be understood. The emergence of single cell and spatial transcriptomics offers a ........

• • Small Molecule Discovery

  Small molecule discovery is a critical methodology in biomedical research, aiming to identify, optimize, and validate biologically active compounds from the vast and complex chemical space. These compounds are typically low-molecular-weight organic molecules capable of modulating protein activity, signaling pathways, or cellular functions, thereby contributing to advancements in drug development, chemical biology, and precision medicine. The primary objective of small molecule discovery is to identify......

• • PROTACs and Molecular Glues

  PROTACs and molecular glues represent a class of small-molecule therapeutics with a revolutionary mode of action. They function by recruiting intracellular target proteins to E3 ubiquitin ligases, thereby promoting the ubiquitination of the targets and their subsequent degradation via the proteasome. This approach surpasses the conventional paradigm of merely inhibiting protein function, enabling direct elimination of disease-associated proteins and offering a novel strategy for addressing previously.......

• • PROTAC Degradation

  PROTAC degradation represents an innovative approach to precise protein regulation, leveraging the endogenous ubiquitin–proteasome system to selectively degrade target proteins and thereby inhibit their function. Unlike traditional small-molecule inhibitors that merely suppress protein activity, PROTAC degradation removes the target protein entirely from the intracellular environment. A PROTAC (Proteolysis Targeting Chimera) is a bifunctional molecule composed of two ligands—one specific for the target.....

• • PROTAC Molecule

  The PROTAC molecule represents an innovative drug discovery strategy designed to selectively degrade intracellular target proteins. Unlike conventional inhibitors that block protein function, PROTAC molecules harness the cell’s endogenous protein degradation machinery to eliminate unwanted or pathogenic proteins. A PROTAC molecule consists of two essential components: a small-molecule ligand that selectively binds to the target protein and another ligand that recruits an E3 ubiquitin ligase. These two......

• • Spatial Single-Cell RNA-Seq

  Spatial single-cell RNA-seq integrates single-cell RNA sequencing with spatial transcriptomics to elucidate the patterns of gene expression within tissues while preserving their precise spatial context. This approach retains spatial information at the cellular level within tissue sections, allowing the simultaneous measurement of individual transcriptomes and their spatial positioning. By bridging transcriptomic data with spatial localization, this technology offers profound insights into cellular.......

• • Protein Folding Assay

  The protein folding assay is a technique employed to investigate the three-dimensional structure of proteins and the mechanisms underlying their folding. The biological function of proteins is largely dependent on their proper folding, while misfolded proteins can result in cellular dysfunction and are implicated in several neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, and Creutzfeldt-Jakob disease. Therefore, protein folding assays hold significant importance in ........
