Nanopartz^TM Accurate^TM brand conjugated spherical gold nanoparticles are manufactured using our proprietary and patent pending method that results in exact sizes, and highly monodisperse sizes and shapes, and adds the added advantage of proprietary polymer caged coating with carboxyl, methyl, amine, biotin, or neutravidin functional groups.  These particles are perfect for customer conjugation to most antibodies and DNA for all in vivo applications.  Nanopartz^TM conjugated gold nanoparticles are the only nanoparticles in the industry that come with a Certificate of Analysis assuring conjugation.  These conjugations have some of the longest shelf lives in the industry - up to six months.

 

Composition

Patented gold colloid with a proprietary polymer caged conjugation with methyl, carboxyl, amine, biotin or neutravidin active groups resulting in a patent pending composition. Proprietary charge control to reduce non-specific binding.   Excess active groups are reduced to less than 0.1% the concentration of the gold nanoparticles.

 

Zeta Potential

 

Conjugation	Charge (mV)
Methyl	0
Carboxyl	-20
Amine	10
Neutravidin	-0.5

 

 

Custom Formulation and Production

 

Quantity

• Neutravidin, methyl, carboxyl, amine, and biotin volumes of 1 mL and 5 mL, OD 50 (concentration is 50x our bare gold nanoparticles), or 50 and 250 OD-mLs, respectively.

• For larger quantities, or for orders amounting over 50 mL per annum, please contact sales for quantity pricing.

Delivery

• Shipped sealed in low retention micro-centrifuge containers.

• All are stored in water at pH=7, except for carboxyl and neutravidin which are stored in DI water plus a dilute buffer and and surfactant.

• Orders come with exact size and concentration calculation, along with a Certificate of Analysis with size, concentration, zeta charge, and peak SPR.

• Most conjugations ship in 1 week.

• All shipments are made Fed Ex Standard Overnight delivery. International orders shipped Fedex Priority 2 day.  No shipments on Fridays.

Part #s

 

      PN# 20-P(A,C,M,N)-SSS-OD

• -P(A,C,M,N) is conjugation; Methyl -PM; Carboxyl -PC; Amine -PA;  Neutravidin -PN

• -SSS is nanoparticle size; 5-100 nm

• -OD is OD-mLs; This product ships in volumes of 1 mL and 5 mL at OD 50 which amounts to 50 and 250 OD-mLs, respectively.

• Example: Accurate Conjugated SGNPs, Carboxyl, 30 nm, 50 OD-mL would be: 20-PC-30-50

Price

• Methyl, Carboxyl, Amine and Biotin 50 OD-mL $440; 250 OD-mL $1760

• Neutravidin 50 OD-mL $480; 250 OD-mL $1920

• Each product comes highly concentrated, 50 times greater than our regular bare gold nanoparticles.  We do this for a number of reasons detailed in our FAQz.  Further, our yield is about 50% so it takes over 100 mL of gold nanoparticles to make 1 mL of concentrated conjugated particles.
