Tumor-Infiltrating Lymphocytes (TILs) are key immune components for targeting and eliminating cancer cells. Their therapeutic potential hinges on the ability to efficiently isolate and expand these cells from limited tumor samples. Traditional methods often require large amounts of tumor tissue and extended culture periods, which can be a bottleneck in preclinical development. Alfa-TILTM offers a next-generation solution for low-input & rapid TIL isolation and expansion, designed to optimize cell yield and quality with minimal tumor input. This service is ideal for early-stage drug discovery and cancer immunotherapy research, where quick turnaround times and small sample volumes are crucial.
The success of preclinical TIL development depends on the ability to reliably isolate and expand functional lymphocytes from limited tumor samples. However, traditional TIL isolation workflows were originally designed for clinical-scale manufacturing and are often not optimized for the constraints of early-stage research—such as small tissue volume, tight timelines, or frequent iteration needs. For preclinical applications, an efficient and reproducible method for isolating TILs from minimal input is critical. Such a method must balance high yield and quality with operational simplicity and speed, while remaining adaptable to a variety of sample types including murine tumors, xenografts, and small human biopsies.

Accelerated Immunotherapy Evaluation
Utilize low-input samples for rapid expansion of functional TILs. This enables efficient screening of novel agents (immuno-oncology drugs, small molecule inhibitors, cytokines, oncolytic viruses) or combination therapies on critical TIL functions – including activation, proliferation, cytotoxic killing, and reversal of exhaustion – significantly shortening candidate therapy assessment timelines.
In-Depth Tumor Immune Microenvironment Profiling
Overcome tissue limitations to efficiently isolate TILs from minimal samples. Supports advanced analyses like single-cell multi-omics sequencing (RNA/DNA/TCR) and deep immunophenotyping, enabling precise characterization of TME heterogeneity, T-cell clonal dynamics, and functional states to aid biomarker discovery and validation.
Empowering Translational Research & Complex Model Studies
Facilitates rapid analysis of TIL dynamics using precious clinical biopsy specimens (e.g., pre/post-treatment pairs), providing insights for clinical translation. Offers feasible TIL research solutions for complex preclinical models like PDX or humanized mice, where tissue availability is constrained.
Alfa-TILTM provides a streamlined, fast, and scalable TIL isolation and expansion service. Our platform is designed to maximize TIL recovery from small tumor specimens, reducing the time required to generate usable TIL populations.

TIL Low-Input Isolation Service
Efficient tumor-infiltrating lymphocyte (TIL) isolation from diverse solid tumor tissues, including murine tumor models, human tumor samples, and PDX specimens. The protocol is optimized for minimal starting material, enabling robust TIL recovery even from highly restricted tissue biopsies in early-stage research.

TIL Rapid Expansion Service
Leveraging a refined expansion platform, this service delivers scalable quantities of functional TIL within a compressed timeline. Expanded cells are immediately compatible with in vitro functional assays and in vivo efficacy studies, providing flexible scale-up and predictable scheduling for downstream applications.
