Host: Donkey Product: IgG, whole molecule Conjugate: Cyanine Cy™5 Product Category: ChromPure™ Purified Proteins from Normal Serums RRID: AB_2337270 ChromPure is our trade name for highly purified proteins from the serum of non-immunized animals. Storage and Rehydration: Store freeze-dried solid at 2-8°C. Rehydrate with the indicated volume of dH2O 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 rabbit anti-donkey whole serum is the same as that against rabbit anti-donkey IgG, Fc fragment specific and rabbit anti-donkey IgG (H+L) Buffer: 0.01M Sodium Phosphate, 0.25M NaCl, pH 7.6 Stabilizer: 15 mg/ml Bovine Serum Albumin (IgG-Free, Protease-Free) Preservative: 0.05% Sodium Azide Cy5 conjugates are excited maximally at 650 nm and fluoresce maximally at 670 nm. They can be excited to about 98% of maximum with a krypton/argon laser (647 nm line) or to about 63% of maximum with a helium/neon laser (633 nm line). Cy5 can be used with a variety of other fluorophores for multiple labeling due to a wide separation of its emission from that of shorter wavelength-emitting fluorophores. However, we recommend Alexa Fluor® 647 as the preferred far-red-fluorescing dye because it is brighter than Cy5 in aqueous mounting media. The reverse is true when mounting in non-polar, plastic mounting media, i.e. Cy5 is brighter than other far-red-fluorescing dyes, including Alexa Fluor® 647 and DyLight 650.This product is for IN VITRO RESEARCH USE ONLY.
