72040-63-2 Usage
Description
Biotin-LC-NHS Ester has an extended spacer arm which helps to minimize steric hindrance. The membrane permeability of this reagent allows it to be used for intracellular labeling. It can react efficiently with primary amino (-NH2) to form stable, irreversible amide bonds.
Chemical Properties
Succinimidyl 6-(biotinamido)hexanoate is White Solid
Uses
Different sources of media describe the Uses of 72040-63-2 differently. You can refer to the following data:
1. Has been used to biotinylate both the antibody and the carrier in the Protein Avidin-Biotin solid surfaces, such as plastics, which may reduce antigenicity. It has also been used to enhance the detection of DNA on nitrocellulose.
Spacer Arm:
2. A biotinylation reagent incorporating an aminocaproyl pacer? This can reduce the steric hindrance in binding avidin to some biotinylated compounds when used to biotinylate both the antibody and the carrier in the Protein Avidin-Biotin Capture Sy
3. Succinimidyl 6-(biotinamido)hexanoate is a biotinylation reagent incorporating an aminocaproyl “spacer”. This can reduce the steric hindrance in binding avidin to some biotinylated compounds when used to biotinylate both the antibody and the carrier in the Protein Avidin-Biotin Capture System. This system avoids the direct interaction of a captured antibody with solid surfaces, such as plastics, which may reduce antigenicity. It has also been used to enhance the detection of DNA on nitrocellulose. Has also been used as a cell surface labelling reagent
Biological Activity
nhs-lc-biotin (succinimidyl-6-(biotinamindo)hexanoate), also known as nhs-x-biotin is a derivative of d-biotin, a amine-reactive biotinylation agent, that contains a spacer arm off the valeric acid side chain of d-biotin with an nhs ester group at its end. the nhs ester group at the end of nhs-lc-biotin covalently binds to amine groups in proteins and other molecules forming a stable amide linkage and releasing the nhs group. the 6-aminocaproic acid spacer of nhs-lc-biotin greatly increases the length between a covalently modified molecule and the bicyclic biotin rings leading to a better binding potential for avidin or streptavidin probes. nhs-lc-biotin is insoluble in aqueous environments requiring the dissolution of organic solvents prior to the addition to a buffered reaction.bioconjugate techniques , 2nd ed. by greg t.hermanson (pierce biotechnology, thermo fisher scientific, rockford, il). academic press (an imprint of elsevier): london, amsterdam, burlington, san diego . 2008. isbn 978-0-12-370501-3.
Purification Methods
Dissolve ~400mg of the ester in dry propan-2-ol (~25mL) with gentle heating. Reduce the volume to ~10mL by gentle boiling and allow the solution to cool. Decant the supernatant carefully from the white crystals, dry the crystals in a vacuum over P2O5 at 60o overnight. This material gives one spot on TLC. [Costello et al.

Check Digit Verification of cas no
The CAS Registry Mumber 72040-63-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,4 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 72040-63:
(7*7)+(6*2)+(5*0)+(4*4)+(3*0)+(2*6)+(1*3)=92
92 % 10 = 2
So 72040-63-2 is a valid CAS Registry Number.

METHODS FOR CONJUGATING NUCLEIC ACIDS WITH SMALL MOLECULES
-
, (2012/07/27)
A method for conjugating a nucleic acid with a molecule is provided. The method includes steps of (a) reacting the nucleic acid having a 5′-monophosphate with an activating agent in a first buffer to form a solution; (b) mixing an alcohol with the solution formed in the step (a) to obtain an intermediate; and (c) dissolving the intermediate in a second buffer containing an ethylenediaminetetraacetic acid (EDTA) and adding a nucleophile thereinto to react the intermediate with the nucleophile.
