Information ChromPure is our trade name for highly purified proteins from the serum of non-immunized animals.Usage Physical State: Freeze-dried solid Storage and Rehydration: Store freeze-dried solid at 2-8°C. Rehydrate with the indicated volume of dH2O (see product specification sheet) and centrifuge if not clear. Prepare working dilution on day of use. Product is stable for about 6 weeks at 2-8°C as an undiluted liquid.Extended Storage after Rehydration: Aliquot and freeze at -70°C or below. Avoid repeated freezing and thawing. Alternatively, add an equal volume of glycerol (ACS grade or better) for a final concentration of 50%, and store at -20°C as a liquid. Expiration date: one year from date of rehydration. The expiration date may be extended if test results are acceptable for the intended use.
Purity:Based on immunoelectrophoresis at an antigen concentration of 20 mg/ml, the pattern of precipitation against goat anti-rat whole serum is the same as that against goat anti-rattransferrin.No precipitin line was detected against goat anti-rat IgG (H+L). Transferrin is manufactured as the iron bound form, commonly referred to as Holo-Transferrin. Buffer: 0.01M Sodium Phosphate, 0.25M NaCl, pH 7.6 Stabilizer:15 mg/ml Bovine Serum Albumin (IgG-Free, Protease-Free) Preservative:None(Warning:Use of sodium azide as a preservative will substantially inhibit the enzyme activity of horseradish peroxidase.) Conjugate Horseradish Peroxidase
Horseradish peroxidase (HRP) conjugates are prepared by a modified Nakane and Kawaoi procedure (J. Histochem. Cytochem. 1974. 22, 1084). Peroxidase conjugates are commonly used for immunohistochemistry, Western blotting, and ELISA. Affinity-purified anti-horseradish peroxidase and conjugates are available for detection of horseradish peroxidase antigen or for signal amplification of HRP-containing reagents. For immunostaining of mammalian cells, an advantage of using anti-horseradish peroxidase is reduced background, since the antibody does not recognize the endogenous peroxidase-like enzymes found in those cells.
