Qdot™ 525 ITK™ carboxyl quantum dot는 biomolecule 부하량이 높아야 하는 맞춤형 conjugate 조제에 이상적인 시작 물질입니다. 이들 물질은 carboxylate 기능을 가지며 EDC-매개 응축을 사용해 단백질의 아민군과 변형 oligonucleotide에 결합할 수 있습니다. 이들 probe의 코팅은 본사 Qdot™ ITK™ amino quantum dot 보다 결합 부위가 많지만 비특이 상호작용을 방지하는 PEG linker가 부족합니다. 이들 물질을 X-PEG-amine bi-functional linker에 접합하여 반응을 맞춤화하고 특이성을 높일 수 있습니다. 본사의 Qdot™ ITK™ carboxyl quantum dots는 8 μM 용액으로 제공되며 Qdot™ 프로브 색상 9개를 모두 이용할 수 있습니다.

Qdot™ ITK™ Carboxyl Quantum Dot의 주요 특징:

• Qdot™ 525 ITK™ carboxyl quantum dot 최대 방출: 525 nm
• 높은 광안정성, 밝은 형광
• 단일 라인 여기원으로 효율적으로 방출
• 좁은 방출 및 넓은 스크로크 변화
• 여러가지 색상으로 구매 가능
• 다양한 라벨링 및 추적 어플리케이션에 이상적

Qdot™ Nanocrystal의 특징
Qdot™ probe는 밝은 형광 신호 및/또는 실시간 추적이 필요한 어플리케이션에 이상적입니다. 형광 시약 중 유일하게 Qdot™ probe의 9가지 색상은 모두 단일 (UV --> 청색-녹색) 광원으로 동시에 여기할 수 있습니다. 이 특성은 사용자가 편리하게 사용할 수 있는 경제적인 multiplexing 어플리케이션에 매우 적합한 시약입니다. Qdot™ label은 반도체 나노기술에 기반하며 중간 크기의 단백질과 크기가 유사합니다.

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.

Find additional tips, troubleshooting help, and resources within our Cell Analysis Support Center.

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.

Optimized linkage and quenching strategies for quantum dot molecular beacons.
Authors:Cady NC, Strickland AD, Batt CA
Journal:Mol Cell Probes
PubMed ID:17084590
Quantum dot (QD) molecular beacons were explored for sequence-specific DNA detection. The effectiveness of multiple linkage strategies and fluorescence quenchers were compared in hybridization-based assays. To compare linkage strategies, covalent amide linkage and streptavidin-biotin binding were used to link semiconductor QDs to molecular beacon DNA. Amide-linked beacons showed a 57% ... More
