Research Areas:
ALC-0159 presents highly mobile surface PEG chains in a dense brush-like conformation, which can form a hydrophilic barrier, reduce non-specific protein adsorption and macrophage uptake, improve colloidal stability, prolong in vivo circulation time, and affect the cellular uptake of LNPs. ALC-0159 dissociates from the surface of mRNA-LNPs under long-term mechanical oscillation stress, thereby reducing steric hindrance, inducing mRNA-LNP fusion, increasing particle size, and releasing unencapsulated mRNA .

Synonyms: Dextran 70; Dextran D70; Dextran T70(MW 64000-76000)
Target:
Research Areas:
DBCO-PEG24-NHS ester is a click chemistry reagent. DBCO-PEG24-NHS ester is a click chemistry PEG reagent containing NHS ester that is able to react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research use only .

Cat. No.: HY-D1635
CAS No.: 194041-66-2
Synonyms: Biotin-XX-SSE
Target:
Research Areas:
Sulfo-NHS-LC-LC-Biotin (Biotin-XX-SSE), a biotin reagent, is used to label the proteins exposed to the external leaflet of intact exosomes and contains a larger spacer arm between the biotin and amine reactive linker. The size of this linker helps to overcome steric hindrance and increases labeling efficiency at the crowded exosome surface .
Cat. No.: HY-112768
Purity: ≥95.0%
Target:
Research Areas:
PEG2000-DMPE is a polyethylene glycol-lipid conjugate combined with phosphatidylethanolamine. PEG2000-DMPE undergoes a conformational transition from mushroom-like to brush-like at a concentration of 7 mol%, thereby exerting multiple functions such as inhibitor, stabilizer and surface defect modifier. PEG2000-DMPE can form a steric hindrance barrier on the vesicle surface to block calcium ion-induced liposome fusion, and dynamically regulate the fusion process through spontaneous transfer rate. PEG2000-DMPE can delay the thinning of foam thin liquid films and smoothly seal surface defects of solid support layers. PEG2000-DMPE can be used in the design and related research of stealth liposomes and micelles .

Target:
Research Areas:
AS6 (3'-Hexylsulfanylabscisic acid) is a PYL antagonist with a Kd value of 0.48 μM for Arabidopsis PYL5. AS6 binds to PYL proteins, and its S-hexyl chain blocks PP2C binding via steric hindrance. AS6 alleviates the inhibitory effect of ABA on seed germination in Arabidopsis and lettuce .
Cat. No.: HY-161116
CAS No.: 2306525-79-9
Research Areas:
AD-5584 is a selective and blood-brain barrier-penetrant ACSS2 inhibitor (IC50 = 0.86 μM). AD-5584 binds to the nucleotide-binding pocket of ACSS2, blocking CoA binding and acetyl transfer through steric hindrance, thereby inhibiting the conversion of acetate to acetyl-CoA. AD-5584 decreases acetyl-CoA levels, lipid droplet content, FASN expression, E2F1, SLC7A11, and GPX4 levels, and reduces E2F1 occupancy at the SLC7A11 promoter. AD-5584 induces ferroptosis, lipid peroxidation, malondialdehyde accumulation, and cell death, and decreases clonogenic survival and proliferative capacity. AD-5584 can be used for research on breast cancer brain metastasis .
