| Short Description | Replacement Cartridge Clip with Double Seal - 4 Pack | Optical Calibration (OPCAL) Cartridge | SDS-MW Analysis Kit |
| Long Description | Replacement red cartridge seals for sealing around capillary entrance and exit. Suitable for use with capillaries with an outer diameter up to 375um and all cartridge types. | A blank cartridge used for UV and PDA detector calibration as well as testing for coolant leaks. | The SDS-Gel MW Analysis Kit is designed for use on the PA 800 Plus and is used for the separation and sizing of protein–SDS complexes using a replaceable gel matrix. The gel is formulated to provide an effective protein sieving range of approximately 10 to 225 kDa. Within this size range, the logarithm of protein molecular mass is linear with its reciprocal electrophoretic mobility, allowing the molecular weight of an unknown protein to be estimated from a standard curve of known protein sizes. This chemistry can also be used to effectively quantify the amount of protein and to determine the purity of a protein product. This kit provides reagent volumes for analysis of 100 samples and includes: • Separation Capillary, 67 cm x 50 µm ID, Bare-Fused Silica, (2) • SDS Gel Separation Buffer, 140 mL • SDS Sample Buffer, 100 mM Tris-HCl, pH 9.0/1% SDS, 50 mL • MW Sizing Standard (10 to 225 kDa), 16 mg/mL, 100 µL • Internal Standard, 10 kDa protein, 5 mg/mL, 0.4 mL • Acidic Wash Solution, 0.1 N HCl, 100 mL • Basic Wash Solution, 0.1 N NaOH, 100 mL |
