Polybrene® Technical Bulletin

Polybrene® is a well-known anti-heparin agent. Also known as 1,5-dimethyl-1,5-diazaundecamethylene polymethobromide and hexadimethrine bromide, this positively charged polymer produces non-specific red blood cell agglutination by neutralizing the red blood cell net negative charge.

Overcoming Aggregation in Solid-phase Peptide Synthesis

The ease of assembly of a given peptide sequence is hard to predict, which makes peptide synthesis challenging. Review methods and reagents for avoiding aggregation in solid-phase peptide synthesis.

Analysis of Pesticides in Turmeric Powder by LC/MS/MS and GC/MS/MS after Cleanup with Dual-Layer SPE Cartridge

Pesticide residue testing of turmeric and other (dried) spices is challenging due to their complex compositions and high matrix. An efficient SPE clean-up can be achieved by a new Dual-layer cartridge.
