The versatility of membrane proteins and their composition mirrors the intricate nature of the cell membrane. As a result, it is a challenge to predict with absolute certainty the optimal SMALP BZ polymer for the solubilization and subsequent stabilization of your membrane protein of interest. Therefore, we offer the SMALP BZ Screening Kit that consists of our  four individual SMALP BZs. This way you can conveniently screen for the best SMALP BZ for your protein before scaling up your assay. The SMALP BZ series was developed in collaboration with Prof. Bert Klumperman from Nanosene, a spinout company of Stellenbosch University in South Africa.
