Lipid-impregnated collodion (nitrocellulose) films have been frequently used as a fusion substrate in the measurement and analysis of electrogenic activity in biological membranes and proteoliposomes. While the method of fusion of biological membranes or proteoliposomes with such films has found
An electrochemical method for quantitative determination of enzyme activity in single cells was developed by scanning a microelectrode (ME) over a nitrocellulose film-covered microreactor with micropores by means of a scanning electrochemical microscope (SECM). Peroxidase (PO) in neutrophils was chosen
The potential of matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry (MS) for the analysis of intact triacylglycerols (TAGs) is generally limited by the extensive in-source prompt fragmentation. The sequential deposition of matrix and TAGs over the stainless steel target

The prototypical death receptor Fas (also known as CD95 or Apo-1) plays an essential role in the maintenance of lymphocyte homeostasis. Propagation of cell death through Fas relies on the formation of a multiprotein complex at the receptor level known
A highly rapid, one-step immunoassay of high sensitivity C-reactive protein (hsCRP) using a biosensor with a vertical flow immunoassay (VFA) was developed. The VFA biosensor was primarily composed of a sample pad, conjugate pad, FTH film and nitrocellulose (NC) membrane
