Non radioactive labeling oligonucleotide?
Non radio active labeling for oligonuleotides include: Biotin-labelled oligonucleotides - this biotin can be used to link the oligonucleotide to streptavidin-protein conjugates, streptavidin affinity columns, or labelled streptavidin. Attachment of a biotin molecule to the 3' terminus can also be used to prevent 3' exonuclease digestion and 3' extension during amplification reactions. Digoxigenin (DIG) is mainly used as a non-isotopic label for DNA and oligonucleotides in a wide range of applications: diagnostics, sequencing, blot applications, and in situ hybridization. The digoxigenin label can be detected with enzyme-linked immunoassays for anti-digoxigenin protein conjugates, and visualized through a chemiluminescent reaction. DNP means 2,4-Dinitrophenyl. DNP can be introduced anywhere in the sequence and on either terminus.DNP is an alternative to digoxigenin in cases where two different genes must be detected together. Oligonucleotides labelled with DNP can therefore be used in analytical tests based on anti-DNP antibodies. For other non radioactive labeling, check this site: www.biosyn.com, they offer various oligonucleotide modifications and labelings.
A charge on a proton?
The charge on a proton is deemed to be POSITIVE. NB The charge on an electron is deemed to be NEGATIVE ( opposite charge) The charge on a neutron is deemed to be ZERO(NO CHARGE).
What is the charge on a electron called?
the charge of a proton is called positive charge neutron- negative charge electron- no charge
What is the charge of anion?
A cation has a positive charge and an anion has a negative charge.
What is proton electric charge?
A proton has a positive electrical charge and an electron has a negative electrical charge.
What is Streptavidin paramagnetic particle?
I think these are magnetic particles coated with streptavidin so that once anything conjugated with biotin binds streptavidin, the whole bound complex can be selectively removed using some sort of magnet.
What has the author Teresa Maria Alvarez-Diez written?
Teresa Maria Alvarez-Diez has written: 'Pre-targeted tumour imaging with streptavidin immunoconjugates of monoclonal antibody CC49 and [111]in-DPTA-biocytin'

How does the charge of electrons differs from the charge of proton?
Electrons have negative charge and protons have a positive charge, neutrons have no charge.
What is ranking charge pari passu charge 1st charge and 2nd charge?
what ranking charge pari passu?
What particles has a negative charge and which has a positive charge?
Negative charge = electron Positive charge = positron Positive charge = proton
Charge of an atom?
An atom may have a positive charge, a negative charge, or no charge. If it has a non-zero charge, it is said to be an ion.
What are the kinds of electric charge?
The kinds of electric charge are positive charge and negative charge
Does cyanide have a positive charge?
no, it has a negative charge

The charge on a proton is deemed to be POSITIVE. NB The charge on an electron is deemed to be NEGATIVE ( opposite charge) The charge on a neutron is deemed to be ZERO(NO CHARGE).
Why the nucleus doesnt have charge?
It has a charge on it. it has a positive charge on it.
What kind of charge is a battery charge?
