Targeting the Ets Binding Site of the HER2/neu Promoter with Pyrrole-Imidazole Polyamides [PDF]

, 2000
Three DNA binding polyamides (1-3) were synthesized that bind with high affinity (Ka = 8.7·10^9 M^-1 to 1.4·10^10 M^-1) to two 7-base pair sequences overlapping the Ets DNA binding site (EBS; GAGGAA) within the regulatory region of the HER2/neu proximal ...

Preparation of Thermoplastic Polyimide Ultrafine Fiber Nonwovens by Electrospinning

Cailiao gongcheng, 2018
The superfine fiber of thermoplastic polyimide(LPI), whose average diameter ranges from 0.36μm to 1.47μm, was prepared through electrospinning with DMAc as solvent. It lays a good foundation for the mass preparation of LPI non-woven.

Impact behaviour of nylon-rubber blends: 4. Effect of the coupling agent, maleic anhydride [PDF]

, 1989
Blends of 90 wt% nylon-6 and 10 wt% EPDM (ethylene propylene diene monomer) rubber were prepared. The rubber was grafted with various amounts of maleic anhydride (MA) with the aid of a peroxide.
