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).

The membrane-bound histidine acid phosphatase TbMBAP1 is essential for endocytosis and membrane recycling in Trypanosoma brucei.
Authors:Engstler M, Weise F, Bopp K, Grünfelder CG, Günzel M, Heddergott N, Overath P
Journal:J Cell Sci
PubMed ID:15855239
'In the parasitic protozoan Trypanosoma brucei, endocytosis and exocytosis occur exclusively at an invagination of the plasma membrane around the base of the flagellum, called the flagellar pocket, which actively communicates by vesicular membrane flow with cisternal/tubulovesicular endosomes. The division of the cell surface into three morphologically distinct sub-domains and ... More
Cyclin I protects podocytes from apoptosis.
Authors:Griffin SV, Olivier JP, Pippin JW, Roberts JM, Shankland SJ
Journal:J Biol Chem
PubMed ID:16847066
'The limited regenerative capacity of the glomerular podocyte following injury underlies the development of glomerulosclerosis and progressive renal failure in a diverse range of kidney diseases. We discovered that, in the kidney, cyclin I is uniquely expressed in the glomerular podocyte, and have constructed cyclin I knock-out mice to explore ... More
Identification of nicotinic acetylcholine receptor recycling and its role in maintaining receptor density at the neuromuscular junction in vivo.
Authors:Bruneau E, Sutter D, Hume RI, Akaaboune M
Journal:J Neurosci
PubMed ID:16251443
'In the CNS, receptor recycling is critical for synaptic plasticity; however, the recycling of receptors has never been observed at peripheral synapses. Using a novel imaging technique, we show here that nicotinic acetylcholine receptors (AChRs) recycle into the postsynaptic membrane of the neuromuscular junction. By sequentially labeling AChRs with biotin-bungarotoxin ... More
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
