Alpha Lifetech has established mature antibody discovery platforms based on M13, T4, and T7 phage display technologies, supporting the construction and screening of diverse antibody libraries with capacities up to 10⁸–10⁹ variants. Our platforms enable the discovery of antibodies through multiple approaches, including phage display, hybridoma technology, and single B cell screening.

In addition to antibody discovery, Alpha Lifetech provides customized antibody engineering services, including antibody humanization, affinity maturation, antibody-drug conjugate (ADC) design support, and CAR-T related antibody sequence optimization. Through integrated discovery and development workflows, we deliver reliable antibody solutions for biomedical research and drug development.

Phage display Technology

Phage display technology is a powerful antibody discovery platform that enables the generation and selection of antigen-specific antibodies from diverse antibody libraries. Compared with traditional hybridoma approaches, phage display provides an efficient in vitro screening strategy for identifying antibodies with desired specificity and affinity.

Alpha Lifetech provides comprehensive phage display antibody development services, covering antibody library construction, screening, sequencing, engineering, and functional validation. Our platforms support multiple antibody formats, including scFv, Fab, and recombinant antibody fragments, for applications in biomedical research and therapeutic development.

By integrating antibody engineering and affinity maturation technologies, Alpha Lifetech supports antibody optimization through targeted mutation design, high-throughput screening, and sequence analysis. These approaches enable the identification of improved antibody candidates with enhanced affinity, specificity, and functional performance.

Alpha Lifetech offers the construction and screening of various phage display libraries, including immune libraries, naïve libraries, semi-synthetic libraries, and synthetic libraries. Our platforms utilize commonly used phage systems, including M13, T4, and T7 phage display, with library capacities up to 10⁹ variants. We provide customized antibody discovery workflows to support the identification of high-quality antibody candidates for diverse research and development applications.

Phage Display Antibody Production Workflow

Steps	Service Content	Timeline
Step 1: Animal Immunization	Selected animals are immunized with target antigens using optimized immunization strategies. Serum samples are collected and analyzed by ELISA to evaluate immune response and antibody titers. Following successful validation, immune cells are collected for antibody library construction.	10 weeks
Step 2: cDNA Preparation	Total RNA is extracted from immune cells, followed by reverse transcription and high-fidelity PCR amplification to obtain antibody gene fragments for library construction.	1 day
Step 3: Antibody Library Construction	Antibody gene fragments are cloned into phage display vectors and introduced into suitable host cells to generate diverse antibody libraries. Library quality is evaluated through sequence analysis and quality control assays before phage amplification and preparation.	3-4 weeks
Step 4: Antibody Library Screening	Antibody libraries undergo multiple rounds of panning and screening to enrich antigen-specific binders. Positive clones are identified through ELISA and sequence analysis, followed by further characterization and antibody production.	4-5 weeks
