The Ideal Features of IP PoE Extender

Smart Cabling & Transmission Corp. is a reputed supplier of CCTV security system providing IP PoE extender, video balun, surge protector, HDMI DVI VGA over IP, HDMI extender, and VGA extender. The IP PoE extender is highly designed to extend Ethernet data transmitting/receiving while providing power to your Power Device via PoE (Power over Ethernet) without any other power sources.  

The IP PoE extender is designed to extend any TCP/IP devices for long range transmission up to 1.2Km over existing cost effective CAT5 cable. It is completely transparent to protocols, codes, and applications ensuring compatibility with any IP camera and its management software. Further, the IP extender is a perfect solution for sending IP video links to remote camera installation that are beyond the 100 meters distance limit of Ethernet.

What is R-phycoerythrin and Its Advantages?

Phycobiliproteins are stable and water-soluble proteins derived from cyanobacteria and certain algae. As a family of proteins, it has excellent stability, extremely high quantum efficiencies, and highly-water-soluble. Adopting all the advantages of R-phycoerythrin in research or laboratory, it is easy to be conjugated to antibodies and other proteins. Further, large stokes shifts since its excitation and emission bands at visible wavelengths.


There are some notice and tips to reserve well R-phycoerythrin. Ship with ice pack as a suspension in 60% saturated ammonium sulfate and 50 mM potassium phosphate, pH 7.0. They are stable when stored at 2 - 8°C for at least one year. Do not freeze phycobiliprotein solutions. What’s more, phycobiliproteins must be centrifuged before use.

Brief Introduction of Streptavidin-RPE

Streptavidin conjugates are widely used together with a conjugate of biotin for specific detection of a variety of proteins, protein motifs, nucleic acids and other molecules since streptavidin has a very high binding affinity for biotin. This streptavidin-RPE conjugate comprises streptavidin (as the biotin-binding protein) with RPE covalently attached (as the fluorescent label).

It is commonly used as a second step reagent for indirect immunofluorescent staining, when used in conjunction with biotinylated primary antibodies. It is a very valuable tool for biotin-streptavidin-based biological assays and tests using flow cytometry, microplate reader and microarray platforms.
