Streptavidin

🥰Excellent
Catalog No. T8781Cas No. 9013-20-1

Streptavidin is a protein derived from the bacterium Streptomyces avidinii, with a molecular weight of approximately 60 kDa as a homologous tetramer. Streptavidin is known for its strong affinity to bind with biotin (Vitamin H or B7). The interaction between biotin and streptavidin is one of the strongest non-covalent interactions known in nature, with a dissociation constant (KD) of approximately 0.01 picomolar. Streptavidin also has immunosuppressive properties.

Product Introduction

Bioactivity
Description
Streptavidin is a protein derived from the bacterium Streptomyces avidinii, with a molecular weight of approximately 60 kDa as a homologous tetramer. Streptavidin is known for its strong affinity to bind with biotin (Vitamin H or B7). The interaction between biotin and streptavidin is one of the strongest non-covalent interactions known in nature, with a dissociation constant (KD) of approximately 0.01 picomolar. Streptavidin also has immunosuppressive properties.
In vitro
Compared to the control group, streptavidin (2-200 μg/mL) significantly inhibits the proliferation of Lewis T cells towards WF, with an inhibition rate of 76%-83% [1].

In Western blot or ELISA, a concentration of 0.1-1 µg/mL is sufficient.

For immunoprecipitation, a concentration of 1-10 µg/mL can be used.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
