98% Pure DLin-M-C3-DMA In Bulk For Sale

Q1: What is the primary advantage of DLin-M-C3-DMA over other ionizable lipids?

에이: DLin-M-C3-DMA is a historically significant and clinically validated lipid. Its key advantage is its proven high potency for 생체 내 siRNA delivery, resulting in effective gene silencing. It was optimized over earlier lipid generations (such as DLin-DMA) to enhance efficacy, establishing the “gold standard” for LNP-based RNAi therapeutics.

Q2: Is your DLin-M-C3-DMA suitable for use in commercial drug products?

에이: Yes. Our DLin-M-C3-DMA is manufactured in accordance with cGMP guidelines, making it a suitable candidate for use in clinical trials and commercial pharmaceutical products. We provide the complete regulatory documentation required for your Drug Master Files (DMFs) or Chemistry, Manufacturing, and Controls (CMC) sections of regulatory submissions.

Q3: What specific documentation do you provide to support regulatory filings?

에이: We provide a comprehensive package with each batch to ensure seamless integration into your quality system:

• 분석 인증서(CoA): Batch-specific data for identity, assay/purity, and related substances.

• 물질안전보건자료(MSDS/SDS): For safe handling, storage, and transportation.

• 안정성 데이터: 요청 시 제품의 유통기한 주장을 뒷받침하는 자료를 제공해 드립니다.

• General Quality Information: Information on the manufacturing site and the quality management system.

Q4: We are an API importer. How do you ensure supply chain integrity and compliance?

에이: We cater specifically to the needs of importers. Our protocols include:

• Unbroken Cold Chain: Certified shipping methods to maintain -20°C storage conditions during transit.

• Complete Export Documentation: We prepare all necessary commercial invoices, packing lists, and certificates to meet international customs and regulatory requirements.

• Consistency: Our rigorous manufacturing controls ensure that every batch you import meets the exact high-quality specifications, reducing regulatory risk.

Q5: How does DLin-M-C3-DMA function within an LNP formulation?

에이: Like other ionizable lipids, DLin-M-C3-DMA is the primary functional component of the LNP. At low pH (during formulation), it is positively charged, enabling efficient encapsulation of negatively charged nucleic acids (siRNA/mRNA). In the bloodstream at physiological pH, it is neutral, reducing toxicity. Once inside the target cell’s acidic endosome, it regains a positive charge, which promotes fusion with the endosomal membrane and release of the nucleic acid payload into the cytoplasm (endosomal escape).

Q6: What is a typical starting formulation ratio for siRNA delivery using DLin-M-C3-DMA?

에이: A widely cited and effective molar ratio for siRNA-LNPs is 50:10:38.5:1.5 (DLin-M-C3-DM : DSPC: Cholesterol: PEG-Lipid). This ratio was used in the development of Patisiran. However, we strongly recommend conducting a Design of Experiments (DoE) to optimize the ratio for your specific payload and target tissue.

Q7: Can DLin-M-C3-DMA be used for mRNA delivery as well as for siRNA delivery?

에이: Absolutely. While it gained fame for its use in siRNA, DLin-M-C3-DMA is also a highly effective ionizable lipid for mRNA encapsulation and delivery. Its mechanism of facilitating endosomal escape benefits both siRNA (to access the RISC complex) and mRNA (to access ribosomes for translation).

Q8: For compounding pharmacies, what are the key handling procedures?

에이: Compounding with this material requires strict adherence to aseptic techniques and proper handling:

• 저장: Must be stored at -20°C or below, under an inert gas (nitrogen) and protected from light.

• Thawing: Allow the vial to warm to room temperature in a desiccator before opening to prevent condensation and hydrolysis.

• 용해도: It is readily soluble in ethanol, which is the standard solvent for LNP preparation via rapid mixing.

• 품질: Using our cGMP-grade materials ensures purity and the documentation necessary for patient-specific preparations.

Q9: What are the shelf life and recommended storage conditions to maintain stability?

에이: The shelf life for our DLin-M-C3-DMA is 24개월 from the date of manufacture when stored in the original, unopened container at -20°C 이하, under an inert atmosphere (nitrogen), and protected from light. We recommend dividing bulk material into single-use aliquots to minimize freeze-thaw cycles and exposure.

Q10: 제형 개발에 대한 기술 지원을 제공하시나요?

에이: Our team possesses deep expertise in lipid nanotechnology. While our primary offering is the high-purity cGMP material, we are available to provide basic technical guidance and supporting data. For extensive formulation development, we can recommend specialized CRO partners.

Q11: How can I request a sample, and what is the minimum order quantity (MOQ)?

에이: We provide evaluation samples to qualified business and institutional partners. Please use the “Request a Quote” button to submit your details. A dedicated sales manager will contact you to discuss your application, sample availability, and MOQ, which is dependent on packaging size and destination.
