What are the Q codes in ham radio?

The Q-code is an international set of abbreviations that was created at the beginning of the last century to simplify radiotelegraph communication. Each code is composed by three letters always starting with Q. Each code can be a question if followed by a question mark or an answer (or statement) if not.

Why do hams say 73?

73 is an old telegraph code that means “best regards”. 73, as well as 88 (which means “hugs and kisses”) are part of the language of ham radio.

What does QST mean in ham radio?

What is a Qsy probe?

Applied Biosystems TaqMan QSY probes are dual-labeled probes used for real-time PCR. TaqMan QSY Probes are designed for optimal sensitivity and performance in multiplex qPCR experiments.

What are the two types of probes?

What is the purpose of a probe?

Definition. A probe is a single-stranded sequence of DNA or RNA used to search for its complementary sequence in a sample genome. The probe is placed into contact with the sample under conditions that allow the probe sequence to hybridize with its complementary sequence.

What is a probe in qPCR?

Probe-based qPCR relies on Taq DNA polymerase 5′–>3′ exonuclease activity and a probe. A probe is a sequence specific oligonucleotide with a reporter dye and a quencher.

How does a PCR probe work?

During the PCR the probe binds downstream of the primer. The probe is then cleaved by the polymerase enzyme during the reaction. By cleaving the probe the reporter and quencher are separated which means that the quencher no longer has its effect over the reporter and the level of fluorescence increases.

What is a hydrolysis probe?

Hydrolysis probes, an overview



Hydrolysis probes are a popular detection chemistry for monitoring sequence-specific amplification in RTPCR. Just like with SYBR Green dye, signal detection is achieved through monitoring an increase in fluorescence as the reaction proceeds.
