Feed Plate (from PS biotech, Aachen, Germany)
Feed plate a controlled-release matrix is fixed at the bottom of each well; nutrients are released through a diffusion driven process. enables higher cell densities to be reached, and mimicks fed-batch processes available in 24 and 96-well format glucose-release plates are available from stock from PS Biotech plates releasing other substrates such as fructose, lactose, maltose or other crystalline substance are available on request. plates are supplied individually wrapped for each type of microplate, versions with three or four different release rates are avalable (see below) small quantities are available via Enzyscreen larger quantities should be purchased directly from PS Biotech
315022:  square-shaped 96 deepwell plate (PP) with glucose matrix indication release rate (medium-dependent): 10 g/L/48h (on basis culture colume of 1 ml) indication release rate (medium-dependent): 13 g/L/48h (on basis culture colume of 0.75 ml) indication release rate (medium-dependent): 17 g/L/48h (on basis culture colume of 0.6 ml; this is the culture volume that Enzyscreen generally advises to use for 96-square deepwell plates) compatible with our sandwich covers CR1296 and CR1396, and clamps CR1700 also available with a 50% higher release rate (order #315013) also available with a 40% lower release rate (order #315028) exact release rates depend on growth medium and temperature release rates in different wells are identical (if the same growth medium is used)
315025:  square-shaped 24 deepwell plate (PP) with glucose matrix indication release rate (medium-dependent): 14 g/L/48h (on basis culture colume of 3 ml) indication release rate (medium-dependent): 17 g/L/48h (on basis culture colume of 2.5 ml) compatible with our sandwich covers CR1224 and CR1324 also available with a 40% higher release rate (order #315029) also available with a 80% lower release rate (order #315017) also available with a 40% lower release rate (order #315024) exact release rates depend on growth medium and temperature release rates in different wells are identical (if the same growth medium is used)
