Spatial Proteome in TME
Relying on the tumor microenvironment center technology platform, Alfa Oncology provides spatial proteome detection and analysis services for TME research, helping researchers successfully achieve their research goals.
Proteins are the direct executors of life activities, so the study of protein structure, localization and protein-protein interactions will provide a direct basis for elucidating the nature of life phenomena. Space is the research level closest to the reality of tumors and microenvironments. At the spatial level, obtaining protein localization expression profiles at the spatial level of tumor tissue is of great value for the analysis of tumor tissue microenvironment, diagnosis and prognosis, and precision medicine. Because tumor spatial proteomes can understand biology including single-cell variation (at protein level and localization), dynamic protein translocation, altered interaction networks, and protein localization in multiple compartments (potentially "part-time" activities). And, the combination of global quantitative data enables the construction and systematic analysis of cellular models in the tumor microenvironment (TME) beyond qualitative descriptions.

With the popularity of spatial concepts, spatial detection technologies developed for proteomes are also competitive. At Alfa Oncology, we have established a mature tumor microenvironment center technology platform, with a group of experienced tumor microenvironment research experts and mature spatial omics technologies. We provide spatial proteome detection and analysis services for the tumor microenvironment (TME).
According to the difference of quantitative methods, Alfa Oncology provides three types of spatial proteomics technologies, namely: spatial proteomic technology based on fluorescence imaging, spatial proteomic technology based on mass spectrometry, and spatial proteomic technology based on sequencing. The several available spatial proteomic approaches are highly complementary, and their respective developmental strengths and limitations make them suitable for different types of applications. It provides a new solution for the study of tumor and microenvironment, protein interaction network and protein spatial translocation.
Alfa Oncology provides fluorescence imaging-based spatial proteome technology services. Its core design consists of two parts: one is the detection reagent, which is composed of a primary antibody labeled with a specific oligonucleotide tag sequence (Barcode); the other is an imaging reagent, which is composed of a Barcode complementary probe labeled with a fluorophore.
Alfa Oncology uses multiple ion beam imaging (MIBI) to provide mass spectrometry-based spatial proteome technology services. Since the mass resolution of the mass spectrometer allows detection of dozens of metal tags without interference, up to 100 target proteins can be detected simultaneously.
Alfa Oncology provides sequencing-based spatial proteome technology services using the digital spatial analysis platform (DSP). The number of targets detectable by DSP has reached 100+, covering functional proteins related to tumor, immunity and nerve.
