常见问题解答 (FAQ)

I am planning to use a fluorescent streptavidin labeled conjugate. What are the storage conditions and shelf life for the lyophilized powder and reconstituted solution?

In the lyophilized powder form, the fluorescent streptavidin labeled conjugate is stable for six months when stored at -20 degrees C, desiccated, and protected from light. The reconstituted solution is stable for approximately six months when stored at 4 degrees C, protected from light, with the addition of sodium azide to a final concentration of 5 mM or thimerosal to 0.2 mM. For longer storage, we recommend dividing the solution into aliquots and freezing at -20 degrees C, protected from light. Avoid repeated freezing and thawing of the solution.

I am planning to use a fluorescent streptavidin labeled conjugate. How should I prepare the working solution of the conjugate?

The fluorescent streptavidin labeled conjugate solution can be made by dissolving the powder in 0.5-1.0 mL of PBS or other suitable buffer. For details, please refer to page 4 of the "Streptavidin and Fluorescent Conjugates of Streptavidin" manual (https://assets.fishersci.com/TFS-Assets/LSG/manuals/mp00888.pdf).

Abstract
Development of homogeneous binding assays based on fluorescence resonance energy transfer between quantum dots and Alexa Fluor fluorophores.
Authors:Nikiforov TT, Beechem JM
Journal:Anal Biochem
PubMed ID:16860286
'We studied the fluorescence resonance energy transfer (FRET) between quantum dots emitting at 565, 605, and 655 nm as energy donors and Alexa Fluor fluorophores with absorbance maxima at 594, 633, 647, and 680 nm as energy acceptors. As a first step, we prepared covalent conjugates between all three types ... More
Interaction of the selectin ligand PSGL-1 with chemokines CCL21 and CCL19 facilitates efficient homing of T cells to secondary lymphoid organs.
Authors:Veerman KM, Williams MJ, Uchimura K, Singer MS, Merzaban JS, Naus S, Carlow DA, Owen P, Rivera-Nieves J, Rosen SD, Ziltener HJ
Journal:Nat Immunol
PubMed ID:17401367
'P-selectin glycoprotein ligand 1 (PSGL-1) is central to the trafficking of immune effector cells to areas of inflammation through direct interactions with P-selectin, E-selectin and L-selectin. Here we show that PSGL-1 was also required for efficient homing of resting T cells to secondary lymphoid organs but functioned independently of selectin ... More
Reversibility of covalent electrophile-protein adducts and chemical toxicity.
Authors:Lin D, Saleh S, Liebler DC,
Journal:Chem Res Toxicol
PubMed ID:19548357
The biotin-tagged electrophiles 1-biotinamido-4-(4'-[maleimidoethylcyclohexane]-carboxamido)butane (BMCC) and N-iodoacetyl-N-biotinylhexylenediamine (IAB) have been used as model electrophile probes in complex proteomes to identify protein targets associated with chemical toxicity. Whereas IAB activates stress signaling and apoptosis in HEK293 cells, BMCC does not. Cysteine Michael adducts formed from BMCC and nonbiotinylated analogues rapidly disappeared ... More
Dynamin 2 mutations associated with human diseases impair clathrin-mediated receptor endocytosis.

Journal:Hum Mutat
PubMed ID:19623537
Dynamin 2 (DNM2) is a large GTPase involved in the release of nascent vesicles during endocytosis and intracellular membrane trafficking. Distinct DNM2 mutations, affecting the middle domain (MD) and the Pleckstrin homology domain (PH), have been identified in autosomal dominant centronuclear myopathy (CNM) and in the intermediate and axonal forms ... More
Identification and structural basis of binding to host lung glycogen by streptococcal virulence factors.
Authors:van Bueren AL, Higgins M, Wang D, Burke RD, Boraston AB
Journal:Nat Struct Mol Biol
PubMed ID:17187076
The ability of pathogenic bacteria to recognize host glycans is often essential to their virulence. Here we report structure-function studies of previously uncharacterized glycogen-binding modules in the surface-anchored pullulanases from Streptococcus pneumoniae (SpuA) and Streptococcus pyogenes (PulA). Multivalent binding to glycogen leads to a strong interaction with alveolar type II ... More
