Streptavidin is a biotin-binding protein found in the culture broth of the bacterium Streptomyces avidinii. Like its namesake avidin, streptavidin binds 4 moles of biotin per mole of protein with a high affinity virtually unmatched in nature (Kd~10-15). Streptavidin lacks carbohydrate side chains present on avidin...

Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months...

Streptavidin/FITC can be used in conjunction with biotinylated antibodies as an avidin/biotin labeling system for flow cytometry. Streptavidin (MW ~66kD) binds specifically with biotin (244D). It is derived from the bacterium Streptomyces avidinii and bears a remarkable similarity to chicken egg-white avidin both in...

Streptavidin (MW ~66kD) binds specifically with biotin (244D). It is derived from the bacterium Streptomyces avidinii and bears a remarkable similarity to chicken egg-white avidin both in three-dimensional structure and its ability to bind biotin with extremely high affinity (Kd=10e-15M). It is a tetrameric protein...

Streptavidin is a non-glycosylated polypeptide chain having a molecular mass of 240kD and containg 4 subunits each with a binding site for biotin. The neutral isoelectric point of Streptavidin and the high affinity of the biotin-streptavidin interaction result in a very quick reaction with a high signal to noise...

Stem Cell Factor (SCF) is a glycoprotein that plays a key role in hematopoiesis acting both as a positive and negative regulator, often in synergy with other cytokines. SCF binds to and activates the SCF receptor (SCFR), a receptor tyrosine kinase. SCF stimulates the proliferation of mast cells and is able to...

Recombinant Human SCF produced in insect cells is a single, glycosylated polypeptide chain containing 165aa and having a molecular mass of 118.41kD containing a C-terminal His-tag (6x His). Biological Activity: The ED50 as determined by the dose-dependent stimulation of Human TF-1 cells is typically 2-5ng/ml....
