2D Tumor Modeling Services

Inquiry

Two-dimensional (2D) tumor models have long been a cornerstone of cancer research, providing researchers with a convenient and cost-effective platform for studying fundamental aspects of tumor biology and evaluating potential therapeutic interventions. At Alfa Cytology, we leverage our expertise and cutting-edge technologies to develop highly reproducible and reliable 2D tumor models that enable researchers to gain valuable insights into tumor initiation, progression, and response to treatment.

Introduction into 2D Tumor Modeling

Traditional 2D cell culture systems involve the growth of tumor cells on flat surfaces, such as tissue culture plates or flasks, in a monolayer format. While simplistic in nature, these models offer several advantages, including ease of use, scalability, and cost-effectiveness. They provide researchers with a controlled environment to study key aspects of tumor biology, including cell proliferation, migration, invasion, and response to therapeutic agents.

Commonly Used 2D Cancer Models

Monolayer Cell Cultures: Cancer cells grown as a single layer on tissue culture plates or dishes.
Transwell Assays: Utilizes porous membrane inserts to study cell migration, invasion, and interaction between different cell populations.
Scratch Assays: Involves creating a "scratch" or wound in a monolayer of cells to study cell migration and wound healing.
Clonogenic Assays: Measures the ability of single cancer cells to form colonies when plated at low densities.
Soft Agar Assays: Evaluates the anchorage-independent growth of cancer cells in a semi-solid agar matrix, mimicking tumorigenicity in vitro.

Our Services

At Alfa Cytology, our 2D tumor modeling services cater to a wide range of research applications, from basic mechanistic studies (including kinase-target investigations supported by our kinase engineered Ba/F3 cell line services) to high-throughput drug screening assays. By leveraging optimized protocols, quality-controlled processes, and clinically relevant patient-derived cell line (PDC) model development services, we ensure the reproducibility, translational relevance, and reliability of our tumor models. This integrated approach enables researchers to obtain accurate and interpretable data for both preclinical discovery and therapeutic development projects.

Cell Culture Services

Establish reliable 2D tumor models through routine culture, primary cell isolation, and insect cell expression, supported by STR authentication and mycoplasma testing for consistent preclinical evaluation.

Cell Transfection Services

Construct transiently or stably modified tumor models via lipid-based, PEI, electroporation, or lentiviral methods to support gene function and protein production studies.

Transient Cell Line Construction Services

Rapidly construct transient expression tumor models within days, without genomic integration, for early-stage gene function validation and small-scale protein production.

Stable Cell Line Construction Services

Generate overexpression, reporter gene, polyclonal, and monoclonal stable tumor models with full quality validation to support long-term studies and regulatory submissions.

Knockout Cell Line Construction Services

Generate precise loss-of-function tumor models using CRISPR/Cas9 gene knockout technology, with rigorous sgRNA design, off-target analysis, and Western blot validation.

Knockin Cell Line Construction Services

Precisely knocks in point mutations, reporter genes, or functional cassettes via CRISPR/Cas9-mediated HDR to mimic clinical resistance or track cellular behaviors.

Point Mutation Cell Line Construction Services

Introduces clinically relevant point mutations (e.g., EGFR T790M, KRAS G12D) via CRISPR/Cas9-mediated HDR to generate isogenic cell lines for targeted therapy screening and resistance mechanism studies.

sgRNA Library Cell Pool Construction Services
