| Pulsar® 650 chemistry consists of a Ru(bpy)3+2 metal-ligand complex attached to a linker arm which is attached to a modified C nucleoside. The nucleoside is conjugated to CPG via a succinate linkage. Pulsar 650 CPG can be used for the synthesis of 3'-labeled oligonucleotides on any DNA synthesizer according to standard oligonucleotide synthesis procedures. Pulsar 650 has a very large Stokes' shift with an absorption maximum at 450 nm and an emission maximum at 650 nm. Unlike most oligonucleotide dye labels, the Pulsar 650 label has a larger extinction coefficient at 260 nm than the lambda max at 460 nm.
Pulsar® 650 dye is a fluorophore designed especially for use on the LightCycler® 1.2 and 2.0 real-time qPCR instruments. In addition to its value in real-time PCR, Pulsar 650 is also useful for electrochemiluminescence, electrochemical detection, redox reactions, chemiluminescence and time-resolved luminescence.
LightCycler Users-
Users of the LightCycler 1.2 and 2.0 can set up and run duplexed assays on your instrument by using two BHQ® Probes. Calibration is required for first time users. Additionally, LightCycler 2.0 users will need to spike FAM calibration dye into their Pulsar 650 capillaries. Please visit www.biosearchtech.com for details on duplexing on the LightCycler. |

| 产品用途： |
| Cleavage conditions:Use concentrated ammonia for 90 minutes at 25 °C when using standard amidites or 1:1 ammonia:methylamine (AMA) for 25 minutes at 25 °C when using fast deprotecting amidites.Deprotection conditions:When using fast deprotecting amidites (eg. C-Ac, G-DMF, G-PAC) use concentrated ammonia for 1 hour or AMA for 30 minutes at 60 °C. When using standard amidites (eg. C-Bz, G-iBu) use concentrated ammonia for 5 hours.Fluorescent lifetime: ca.1 microsecond Users of the LightCycler 1.2 and 2.0 can set up and run duplexed assays on your instrument by using two dual-labeled BHQ probes as follows:
Probe 1: 5' FAM/3' BHQ-1 for detection in the 530 nm (F1) channel
Probe 2: 5' BHQ-2/3' Pulsar-650 for detection in the 705 nm (F3) channel
LightCycler 1.2 Users: To successfully duplex Pulsar 650 and FAM probes, a universal Color Compensation file (CC file) must be downloaded and installed onto your hard drive. This file instructs the LightCycler 1.2 to subtract any crosstalk from these reporters outside their designated channels.
LightCycler 2.0 Users: Because the LightCycler 2.0 seeks FAM fluorescence from each capillary during the optics optimization, FAM calibration dye needs to be spiked into any capillary that is lacking a FAM probe, including Pulsar 650 singleplex reactions. We recommend spiking the calibration dye to a final concentration of 10 nM. Please inquire about the availability of this calibration dye. To successfully duplex Pulsar 650 and FAM probes an experimental file (.ixo) needs to be imported into your LightCycler software (version 4.0). This file instructs the LightCycler to subtract any crosstalk from these reporters outside their designated channels.
As alternatives to using the provided files, CC objects can also be generated using dual-labeled probes or T10 calibration dyes (inquire about availability).
