Qdot™ 565 ITK™ amino (PEG) quantum dot는 매우 밝고 광안정성이 높은 형광 라벨 단백질과 기타 biopolymer의 맞춤 제조에 이상적인 시작 물질입니다. 이들 probe는 아민이 비활성화된 PEG로 기능하여 비특이적 상호작용를 방지하고 conjugation을 편리하게 취급할 수 있습니다. 이 amino quantum dot는 EDC 등과 같은 수용성 carbodiimide를 사용해 isothiocyanates 및 succinimidyl esters 또는 native carboxylic acid와 효율적으로 반응합니다. 이런 파생물은 초강력 밝기와 형광 안정성을 요하는 다양한 어플리케이션 라벨링과 추적에 사용할 수 있습니다. Our Qdot™ ITK™ amino quantum dot는 8 μM 용액으로 제공되며 8가지 색상 Qdot™ probe로 구매가능합니다.

Qdot™ ITK™ Amino Quantum Dot의 주요 특징:

• Qdot™ 565 ITK™ amino quantum dot 최대 방출: 565 nm

자주 묻는 질문(FAQ)

How large are the Qdot nanocrystals?

The core/shells are only a few nanometers in diameter (some are elliptical), but with the outer polymer coatings, a fully-functionalized Qdot nanocrystal can range from 15 to 21 nm in hydrodynamic diameter, similar in size to some proteins.

What is the best way to remove white precipitate from my ITK Qdot nanocrystals?

Spinning your ITK Qdot nanocrystals at approximately 3,000 rpm for 3-5 minutes should remove the white precipitate from the supernatant. Use the supernatant immediately.

I see a white precipitate in my ITK Qdot nanocrystals; should I be concerned?

The precipitate in the organic ITK Qdot nanocrystals occurs with some frequency. The ITK Qdot nanocrystals sometimes include impurities that show as a white precipitate.

Why do my Qdot nanocrystals appear to be blinking?

Blinking is an inherent property of quantum dots; in fact, all single-luminescent molecules blink, including organic dyes. The brightness and photostability of Qdot nanocrystals makes the blinking more visibly apparent. Under higher energy excitation, Qdot nanocrystals blink even faster.

My Qdot nanocrystals were brightly fluorescent before I mounted my samples; now I'm seeing a loss of fluorescence. Why is this happening?

Appropriate mounting media selection is very important to retain the fluorescence of Qdot nanocrystals. In our studies, Qdot nanocrystals work best with the following mountants:

HistoMount medium (Cat No. 00-8030); best for long term archiving
Cytoseal 60 Mountant
Clarion Mountant
Most polyvinyl alcohol-based mountants (limited storage time, less than weeks)
Water-based mountants (limited storage time, less than week)
Up to 50% glycerol (limited storage time, less than week)
Note: We do not recommend using ProLong mounting media with Qdot nanocrystals as it will quench their fluorescence.

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

Quantum dot targeting with lipoic acid ligase and HaloTag for single-molecule imaging on living cells.

Authors:Liu DS, Phipps WS, Loh KH, Howarth M, Ting AY,

Journal:ACS Nano

PubMed ID:23181687

'We present a methodology for targeting quantum dots to specific proteins on living cells in two steps. In the first step, Escherichia coli lipoic acid ligase (LplA) site-specifically attaches 10-bromodecanoic acid onto a 13 amino acid recognition sequence that is genetically fused to a protein of interest. In the second ... More

Imaging a single quantum dot when it is dark.

Journal:Nano Lett

PubMed ID:18671437

'We have succeeded in recording extinction images of individual cadmium selenide quantum dots at ambient condition. This is achieved by optimizing the interference between the light that is coherently scattered from the quantum dot and the reflection of the incident laser beam. The ability to interrogate the dot in the ... More

Real-time imaging of astrocyte response to quantum dots: in vivo screening model system for biocompatibility of nanoparticles.

Authors:Maysinger D, Behrendt M, Lalancette-Hébert M, Kriz J

Journal:Nano Lett

PubMed ID:17638392

Astrocytes are the principle macroglial brain cells. They are activated by different stressors and brain injuries. Quantum dots (QDs) can cause oxidative stress. This study shows a real-time imaging of primary cortical cultures and assessment of QD-induced activation of astrocytes in the brains of transgenic mice with the luciferase gene ... More

Variables influencing interactions of untargeted quantum dot nanoparticles with skin cells and identification of biochemical modulators.

Authors:Ryman-Rasmussen JP, Riviere JE, Monteiro-Riviere NA

Journal:Nano Lett

PubMed ID:17408303

Skin cells (NHEK) take up untargeted quantum dots (QD) with surface polyethylene glycol (PEG), amines, and carboxylic acids, but the mechanisms are unknown. Time courses of QD-NHEK interactions were determined and effects of QD surface coating, temperature, culture medium supplements and inhibitors of the cell cycle and endocytosis identified. The ...
