? What is POLY-HRP-STREPTAVIDIN: A proprietary polymer of HRP
(horseradish peroxidase) conjugated to Streptavidin in various polymerization
ranges. (20, 40 & 80). The POLY-HRP-SA product line can be used with
virtually any biotin labeled product including probes & primary and
secondary antibodies. It can replace the conventional streptavidin-HRP
conjugates currently in use. It will activate your current HRP substrates
including the sensitive TMB products (ELISA and blotting), DAB, luminol etc....
? What is POLY-HRP80-GAM:
A new specialty conjugate made with our POLY-HRP80 base. It is a goat
anti-mouse (IgG + IgM) affinity absorbed antibody that is specially conjugated
with our POLY-HRP 80 molecule. Its applications include sensitive histochemical
applications and for use in various immunoassays.
? How does it work: With conventional conjugates, you have only
one or two HRP molecules available to react with your substrate. With POLY-HRP
conjugates you increase the number of HRP molecules by 5X, 10X and even more
(depending upon the polymerization range used). The more HRP molecules
available, the greater the activation of your substrate=the more sensitivity
you obtain!
? How is it supplied: The POLY-HRP-SA is supplied in a
concentrated form of approx 1 milligram conjugate in 1ml of 50% glycerol/
buffer. It should be stored at -20 DEG C and fresh dilutions made daily. The
undiluted stock is good for at least one year. The working dilution required
will depend upon your assay characteristics. We recommend starting dilutions of
1:500 for blotting and 1:2000 for ELISA work. Working titers can then be
derived to optimize your assay.
-POLY-HRP80-GAM is supplied as approx 200ug conjugate in 1ml of
50% glycerol/buffer. It should also be stored at -20 DEG C with fresh dilutions
made daily. It must be titered for each application with initial 1:100-1:1000
dilutions for histochemistry.

and 100ml specially prepared biotin-free casein diluent (cat#RDI-PHRP-DILX)
(limited one per customer)
strating dilutions of 1:5000 for ELISA recommended (most assays seem to work
best at 1:5000-1:10,000, which would be the 1 milligram stock diluted to 1
Liter of conjugate!) See our HRP-conjugate stabilizer for long term diluted
storage and our casein buffers for lower backgrounds.
-ideal for poly-HRP conjugates and conventional HRP conjugates diluted to working strength!

SA3-RHT will provide real-time stability to ready-to-use SA-PolyHRP conjugates at +2°C/+8°C (beyond one year) and room temperature (at least one year). SA3-RHT will support SA-PolyHRP conjugates also in the very low working strength concentrations down to 200-100-50 ng/ml. It will maintain activity of diluted SA-PolyHRP conjugates in working strength ready-to-use format at a level of 90-to-100% of the initial activity during at least 4 weeks stressing at 37°C. That way SA3-RHT makes SA-PolyHRP suitable for routine clinical IVD applications through finally making it compliant with mandatory IVD requirements on stressed/accelerated reagent stability at elevated temperatures.
