S239l
Overview
Product sourcing insights & recommendations
The phrase 's239l' primarily refers to a specific genetic mutation used in the biotechnology industry to optimize therapeutic antibodies, though it also appears as a product code for electronic components and a legal citation in tax law.
1. Biotechnology: Optimized Fc Variants
In the pharmaceutical industry, S239L refers to a specific amino acid substitution (Serine to Leucine at position 239) in the Fc region of IgG1 antibodies JustiaJustia.
* Purpose: It is a key component in "Fc engineering" to enhance the immune system's ability to kill target cells (such as tumor cells) through Antibody-Dependent Cell-mediated Cytotoxicity (ADCC) Justia.
* Market Trends: The industry is moving toward "next-generation" monoclonal antibodies that use S239L or similar mutations (like S239D/I332E) to overcome low-affinity genetic variations in patients, ensuring cancer treatments work effectively for a broader population Googleapis.
* Clinical Outlook: Several FDA-approved drugs, such as Margetuximab (Margenza) and Tafasitamab (Monjuvi), utilize these optimized variants as a "backbone" for advanced oncology therapies Googleapis.
2. Electronics: S239L IC Components
In the B2B market, S239L is a model number for integrated circuit (IC) chips and electronic components Alibaba.
* Product Insight: These are primarily supplied by electronic distributors in Shenzhen, China Alibaba.
* Applications: They are often listed alongside other ICs for general industrial and consumer electronics applications Alibaba.
