Human TNF-alpha Protein, His Tag (TNA-H5228) is expressed from human 293 cells (HEK293). It carries a polyhistidine tag at the C-terminus, and has a calculated MW of 18.3 kDa. The protein migrates as 17-19 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Biotinylated Human VEGF165, His,Avitag(VE5-H82Q0) is expressed from human 293 cells (HEK293). It carries a polyhistidine tag at the N-terminus, followed by an Avi tag (Avitag™), and has a calculated MW of 22.4 kDa (monomer). The protein migrates as 25-33 kDa (monomer) under reducing (R) condition, and 42-55 kDa (homodimer) under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.

Human Claudin-6 Full Length Protein (VLP) (CL6-H52P7) is expressed from human 293 cells (HEK293). Virus-like particles(VLPs) are formed by self-assembly of envelop/capsid proteins from viruses. Membrane Proteins can be constituted in-situ with VLPs produced from HEK293 cell cultures.

CR 2200 is ideal for anyone who needs to perform routine water analysis tests with small sample amounts, as 5 programs are available for digestion of 12 sample cuvettes at 212, 248 and 298.4 °F (100, 120 and 148 °C).

In addition, you can program the CR 3200 to carry out 8 of your individual digestions at freely selectable temperatures up to 338 °F (170 °C).

CR 4200 is the right choice for anyone who needs to perform multiple tests simultaneously, such as COD (298.4 °F/148 °C) and total-N (248 °F/120 °C), as the two thermoblocks for 12 cuvettes each can be controlled separately. It also has memory for 8 of your own user-defined programs with free temperature selection up to 338 °F (170 °C).
