Cat. No.: HY-Y1219H
CAS No.: 112926-00-8
Silica gel, high-purity grade, 200-400 mesh is a low-density, high-surface-area, high-purity inert additive that can be used to prepare chromatographic column sieve plates based on the sol-gel method. Silica gel, high-purity grade prevents DNA degradation by absorbing water from plant leaves, and is suitable for the preservation of field-collected samples for subsequent DNA extraction, restriction endonuclease digestion, PCR amplification and gene sequencing. It can also be reused after being saturated with water. Silica gel, high-purity grade can provide a non-toxic, inert aquatic environment for embedded cells, allowing nutrients, oxygen and metabolic waste to diffuse freely and blocking external pollution, thereby maintaining the activity of fibroblasts and epithelial cells .

Cat. No.: HY-D0219
CAS No.: 76-61-9
Synonyms: Thymolsulphonephthalein
Thymol blue is a reversible pH indicator that responds to the pH of the solution through structural changes of protonation and deprotonation. Thymol blue is red (HI - form) under acidic conditions and blue (I 2- form) under alkaline conditions. Quantitative detection is achieved through the absorption peak shift (435 nm/596 nm) of the UV-visible spectrum. Thymol blue selectively responds to pH changes, changing from red to yellow at pH 1.2-2.8 and from yellow to blue at pH 8.0-9.6. Thymol blue can be fixed in a silica gel matrix through sol-gel technology to form a solid-state sensor for in-situ pH measurement in the marine environment and acid-base monitoring in the biomedical field[1][2].

Synonyms: DBCO-PEG5000-NH2
DBCO-PEG5000-Amine (DBCO-PEG5000-NH2) is a polyethylene glycol derivative containing dibenzocyclooctyne. DBCO-PEG-Amine is a universal, modular "bridge molecule": it forms stable covalent linkage with target materials (e.g., MSN or polymers) via the amino group at one end, while the DBCO group at the other end enables efficient, specific, and biocompatible click chemical conjugation with any azide-bearing biological entities (e.g., bacteria, cells) in subsequent steps .
