Medchemexpress LLC Hexadecanoic acid, 1-methylethyl ester | 142-91-6 | 99.2% | 298.51 | 25 G
Isopropyl palmitate is a fatty acid ester used for the design and characterization of bioactive bilayer films. These bilayer membranes can scavenge free radicals, inhibit lipid peroxidation, and inhibit the growth of foodborne pathogens. It also serves as an excipient, functioning as a lubricant, oily carrier, solvent, and for controlled-release transdermal films. In microemulsion systems for cosmetics and drug delivery, it acts as an oil phase and a skin penetration enhancer, promoting drug permeability and improving transdermal drug delivery efficacy.

ABclonal Technology MonoMethyl-Histone H3-R8 Rabbit pAb
Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. This gene is intronless and encodes a replication-dependent histone that is a member of the histone H3 family. Transcripts from this gene lack polyA tails, instead, they contain a palindromic termination element. This gene is located separately from the other H3 genes that are in the histone gene cluster on chromosome 6p22-p21.3.
