Purified proteins, C-Reactive protein, human (CRP), >99% purity HU5dm ..........
CRP is isolated from pleural and ascites fluids and sera. Abnormally high levels of serum CRP indicate
acute phase disease states. Polysciences’ CRP is suitable for iodination and for preparation of serum
control standards. Sold as a solution in 0.05 M TRIS buffer containing 0.25M sodium chloride and
0.005M calcium chloride with 0.1% sodium azide. Concentration varies from about 3.4-4.5 mg/mL
and fill volume varies from about 200-300 uL, with every lot containing 1 mg CRP in solution. For
research use only. Not for diagnostic or human drug use. Technical Data Sheet #625
SRfluor Dyes
SRfluor Dyes belong to the family of squaraine rotaxane dyes which exhibit absorption and
emission properties in the far-red region of the spectrum. Provided in crystalline powder form.
Spectral properties:
abs. max. = 650nm & em. max. = 678nm in DMSO.
Please see website for individual spectra.
Advantages:
• 5-20 times brighter compared to Cy5, Alexa ® and Atto dyes
• More photostable compared to Cy5, Alexa ® and Atto dyes
• Sharp absorption and fluorescence emission profiles
• Available with a range of functionalities to allow conjugation with biomolecules for
in vitro and in vivo imaging
• Other analogs with ability to label the intracellular lipid regions of cells or bind to metal

injections of S.aureus and E. coli that were
prelabeled with SRfluor probe. The entire animal
was irradiated with filtered light at l=625 ±40
nm and an image with emission intensity at
l=670 ±20 nm was collected by a CCD camera
during a 5 second acquisition period. Image
