Phycoerythrins, R-phycoerythrins CAS 11016-17-4

Yam khoom:

Structure: Cov qauv molecular yog ib qho tetra-pyrrole compound, uas yog linearly txuas los ntawm cov saw qhib thiab cov cab kuj protein txuas los ntawm thioether daim ntawv cog lus. Molecular hnyav: txog 170,000 daltons Purity: Amax / A280 > 5.5 Kev nqus siab siab tshaj plaws: 480/565+5 NM Fluorescence emission peak: 575 +5 NM

Khoom kom zoo dua

1. Nrog rau qhov dav dav dav dav hauv PH ntau, nws yooj yim dua los xaiv qhov tsim nyog excitation wavelength kom tau txais kev ua haujlwm siab fluorescence emissions, thiab muaj cov fluorescence emission peaks thaum excitation tshwm sim.

2. Kev nqus thiab fluorescence quantum tawm los yog siab, fluorescence muaj zog thiab ruaj khov, thiab rhiab heev.

3. Nws muaj me me fluorescence keeb kwm yav dhau, tsis yooj yim rau quenching, thiab muaj lub sij hawm ntev fluorescence preservation.

4. Cov dej solubility zoo heev, yooj yim rau kev sib txuas nrog lwm cov molecules, tsis tshua muaj adsorption;

5. Kev tshem tawm cov khoom siv dej ntshiab huv, tsis muaj tshuaj lom thiab muaj kev phiv, tsis muaj xov tooj cua, muaj kev nyab xeeb heev rau kev khiav lag luam thiab siv. Nws yog ib qho yooj yim los ua ke nrog cov tshuaj tiv thaiv kab mob, biotin, affinity, immunoprotein thiab lwm yam tshuaj los ua fluorescent probes.

Qhov chaw thov

1. Txhawm rau sau cov tshuaj tiv thaiv kab mob, biotin thiab streptavidin lossis lwm cov proteins ua fluorescent probes rau immunofluorescence, immunohistochemistry, flow cytometry thiab hauv vivo imaging thwmsim.

2. Cov kev tshawb fawb tau pom tias phycoerythrin yog cov tshuaj photosensitive tshiab uas muaj kev ua haujlwm siab thiab tsis muaj tshuaj lom, thiab nws yuav tsum tau tsim los ua cov tshuaj photodynamic tshiab nrog cov txiaj ntsig zoo (inhibition ntawm cov qog).

3. Phycoglobin, raws li cov xim ntuj, tsis muaj tshuaj lom thiab tuaj yeem siv dav hauv cov tshuaj pleev ib ce, khoom noj khoom haus thiab kev noj qab haus huv.
