Casein is a milk-derived substance routinely used in blocking buffers for Western, Southern and Northern Blot procedures. Blocking agents are used to reduce non-specific binding of detection reagents to the membranes.
Application
Suitable as a blocking Buffer for Western, Southern and Northern Blot membranes. Blocked membranes can then be used in either chemiluminescent, colorimetric, or DIG detection assays.
Features and Benefits
Better blocking performance than dried milk or BSA
Compatible with neutral and positively-charged membranes
Compatible with chemiluminescent, colorimetric , and DIG detection assays
Preparation Note
Dissolve entire contents of bottle in 800 mL molecular biology grade water. Stir until well mixed, then add water to final volume of 1L. Store at 2-8°C for up to one week.
α1,3-Galactosyltransferase gene-knockout pigs transgenic for porcine cytotoxic T-lymphocyte antigen 4 immunoglobulin (pCTLA4-Ig) have been produced to reduce T-cell-mediated rejection following xenotransplantation. The level of soluble pCTLA4-Ig in their blood was greatly in excess of the therapeutic level in patients, rendering

Many proteins that reside in the cytoplasm bind directly to cell membranes and play roles in signaling, adhesion, metabolism, cell structure, and cell motility. Several of these membrane-binding proteins, especially cytoskeletal proteins, have mechanical functions that result in the transmission

Mutations in patatin-like phospholipase domain-containing protein 6 (PNPLA6) have been linked with a number of inherited diseases with clinical symptoms that include spastic paraplegia, ataxia, and chorioretinal dystrophy. PNPLA6 is an evolutionary conserved protein whose ortholog in Drosophila is Swiss-Cheese
