Staining and Analysis A stock solution of thiazole orange (1 mg/mL) was made in methanol. The stock solution was diluted 1:10,000 in phosphate-buffered saline containing 0.002 M EDTA and 0.02% sodium azide.

We found that the optical properties of the three grades of Teflon® {AF} varied systematically with the {AF} {TFE/PDD} composition. The indices of refraction, extinction coefficient (k), absorption coefficient (α), and absorbance {(A)} increased, as did the {TFE} content, while the {PDD} content decreased. AFDye™ 488 is a bright, and highly photostable, green-fluorescent probe optimally excited by the 488 nm laser line. This probe is water-soluble and its fluorescence is pH independent over a wide pH range. The brightness and photostability of blue dyes are best suited to direct imaging of low-abundance targets. 2015-03-09 · Alexa Fluor® 488 A37570* A20000 A20100 A37563* Alexa Fluor in nm, conjugated to an IgG antibody.

Storage of IgG antibodies Serum Antibodies present in serum is a very stable format for antibody storage. In -20°C or -70°C serum can usually be stored for years, but in some specific cases, this time may be shorter for anti-peptide antibodies.

AFDye™ 488 is a bright, highly photostable, green-fluorescent probe optimally excited by the 488 nm laser line. ‡ Extinction coefficient of the reactive dye at emission maximum in cm-1 M-1. § Human vision is insensitive to light beyond ~650 nm; it is not possible to directly view far-red– and near-IR–fluorescent dyes. Datasheet MSDSs. AFDye™ 488 Picolyl Azide is an advanced fluorescent probe that incorporates a copper-chelating motif to raise the effective concentration of Cu (I) at the reaction site to boost the efficiency of the CuAAC reaction, resulting in a faster and more biocompatible CuAAC labeling. Up to 40-fold increase of signal intensity, compared to conventional azides, was reported (see Selected References).
