Avidin D is isolated from egg white by a specific affinity system which results in a homogeneous, ultrapure avidin with very low nonspecific binding characteristics. Avidin D is recommended for use in solid-phase assays and many histochemical applications when the technique of sequential addition of reagents (“sandwich” technique) is employed.

Specifications

Unit Size 10 mg
Applications Immunohistochemistry / Immunocytochemistry, Immunofluorescence, Elispot, ELISAs
Recommended Usage Dissolve in 0.1 M sodium bicarbonate. The recommended concentration range for use is 5-50 µg/ml.
Recommended Storage 2-8 °C
Molecular Weight 68000
Conjugate Unconjugated
Detection Target Biotin

Streptavidin is a 60 kDa non-glycosylated protein composed of four identical subunits, each of which has a binding site for biotin. Our streptavidin is isolated from Streptomyces avidinii by a specific affinity system which results in a homogeneous, ultrapure streptavidin with very low nonspecific binding characteristics.

Unconjugated streptavidin is recommended for use in solid-phase assays and immunohistochemical applications when the technique of sequential addition of reagents (sandwich technique) is employed. This reagent has also been effectively employed in subtractive hybridization procedures.

Features:

  • Resembles egg white avidin in its biotin binding properties
  • In most applications streptavidin and avidin are interchangeable

Specifications

Unit Size 1 mg
Applications Immunohistochemistry / Immunocytochemistry, Immunofluorescence, ELISAs
Recommended Usage Recommended method of reconstitution: dissolve in 10 mM phosphate, 0.15 M NaCl, pH 7.5. Reconstituted solutions of streptavidin may be preserved with 0.08% sodium azide. The recommended concentration range for use is 5-20 µg/ml.
Recommended Storage 2-8 °C
Conjugate Unconjugated

Avidin DN is isolated by an affinity chromatographic system that results in a form of avidin which, like Avidin DH, exhibits very low nonspecific binding to nucleic acids. Although the reasons for this property are not fully understood, this feature can be exploited when using biotin-avidin detection systems with biotin-labeled DNA or RNA probes for in situ or nitrocellulose hybridization techniques.

Specifications

Unit Size 1 mg
Applications In situ hybridization, Blotting Applications
Solution 50 mM sodium bicarbonate, pH 8.2, preservative
Recommended Usage The recommended concentration range for use is 10-20 µg/ml. This product is designed for use with biotinylated nucleic acids.
Recommended Storage 2-8 °C
Concentration 1.0 mg/ml
Conjugate Unconjugated
Detection Target Biotin
