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:0.05% Sodium Azide Conjugate Cyanine Cy™3
Amax: 550Emax: 570nmCy3 is brighter, more photostable, and gives less background than other orange-red fluorescing dye conjugates. Cy3 conjugates can be excited maximally at 550 nm, with peak emission at 570 nm. For fluorescence microscopy, Cy3 can be visualized with traditional tetramethyl rhodamine (TRITC) filter sets, since the excitation and emission spectra are nearly identical to those of TRITC. We recommend Cy3 as a brighter alternative to TRITC. Cy3 can be excited to about 50% of maximum with an argon laser (514 nm or 528 nm lines), or to about 75% of maximum with a helium/neon laser (543 nm line) or mercury lamp (546 nm line). Cy3 has been used with fluorescein for double labeling; however, the use of a narrow band-pass emission filter for fluorescein is recommended to minimize Cy3 fluorescence in the FITC filter set. Cy3 can also be paired with Alexa Fluor® 647 for multiple labeling when using a confocal microscope. However, a better choice for multiple labeling is Rhodamine Red-X because its fluorescence is midway between a green fluorescing dye (like Alexa Fluor® 488) and a far-red-fluorescing dye like Alexa Fluor® 647.
