If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

General description
Application
Stimuli-Responsive Nanocarriers: Functionalizes mesoporous silica pores to create pH-sensitive "gatekeepers" that trigger drug release specifically within acidic tumor microenvironments.
Gene & Nucleic Acid Delivery: Modulates the surface zeta potential of nanoparticles to facilitate high-efficiency electrostatic loading and endosomal escape of siRNA, mRNA, and pDNA.
Precision Bioconjugation: Acts as a molecular bridge for anchoring targeting ligands (e.g., Folate, RGD peptides) or PEG chains to gold and iron oxide nanoparticles for enhanced circulation and cell-specific uptake.
Advanced Biosensing: Utilized in LSPR-based diagnostics to immobilize antibodies onto gold nanostructures, enabling real-time detection of clinical biomarkers such as C-reactive protein (CRP).
Neuro-Targeting: Recent findings highlight its role in tuning nanoparticle surface charge to improve Blood-Brain Barrier (BBB) permeability via adsorptive-mediated transcytosis

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
