AI Thread Summary
The discussion centers on the confusion surrounding various fluorescence in situ hybridization (FISH) methods, specifically FISH, mFISH, Chromosome painting, BandFISH, and SKY. The user expresses difficulty in understanding the distinctions and purposes of these techniques. FISH involves using a single-strand DNA fluorescence-labeled probe, while mFISH employs multiple probes, each labeled with different colors. Chromosome painting is often compared to mFISH, but there is ambiguity regarding their definitions. BandFISH is characterized by painting entire chromosomes in distinct color bands, and SKY involves painting all chromosomes in different colors for karyotyping purposes. The user seeks clarification on how probes work in these methods, particularly regarding the visualization of specific chromosomes in different colors. They mention that their understanding has improved after finding better online resources. Additionally, they clarify that AS PCR is also referred to as ARMS, indicating a connection between these terms.

I’ve really lost my nerves on this one :(, I have to learn some methods and differences between them, but I can’t manage it. And all I have is an internet as help.

Methods are :
FISH
mFISH
Chromosome painting
BandFISH
SKY

I just can’t establish difference between some of them, purposes.
Especially Chromosome painting, c’mon I don’t get it, one site says it’s basically mFISH, on other something else. :confused:

This is where I am now:

FISH - using singlestrain DNA fluorescence labeled probe (1 probe I guess)
mFISH - using multiple singlestrain DNA fluorescence labeled probes giving different colours
Chromosome painting – same as mFISH ?
BandFISH – painting whole chromosome in different color bands
SKY – painting all chromosomes (with what ?, DNA probes ?) in different colors for cariotyping

And when in FISH picture you see red probe on chromosome you can see whole chromosome painted in blue, is this done by probes of some kind of color specificlu binding for chromosomes (I’ve saw this in other methods too).

Thank You !

Situation is better now, once I found better resources on the net…

p.s. ARMS = ASO ?
 
Update:
AS PCR is also known as ARMS

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
