The immunostaining looks wonderful! ...the highest titer antibody I have ever received."

"I have attached an image of a Western that demonstrates a superb quality of 21st Century Biochemicals antibodies. Thank you for your help in this project and you are welcome to use the image or my name as a reference for your future customers".

All best

Bruce (University of Missouri)
"The Ab is great. We actually only titered it out to 1:20,000 (my experience is that the people in the lab will not dilute more than that anyway, no matter what I tell them) but the signal is completely burned out even at that dilution. I imaging it could be used at 1:100,000 easily".

I have already recommended 21st to another guy.

Take care

"We treated lysates with phosphatase to verify that the sera were indeed specific for the phosphorylated residues. Well, they are! After phosphatase treatment, there is absolutely no cross reactivity! This is just perfect!" Franck Dequiedt, Ph.D., FNRS, Dept. of Cell. and Mol. Biol., FUSAGX, Belgium

BioTech Company - Rhode Island
"Thanks for the quick turn around, the hard work on your end is always appreciated. I should have another 23 peptide order coming your way by the end of the way, just making some final tweaks."

University of Nebraska Medical Center - Omaha, NE
"Having been disappointed by several peptide companies over the last few years, I wanted to tell you that your company has done a wonderful job with our difficult peptides. I really appreciate the customer service and your ability to give us a heads up when a peptide is very difficult allows us to efficiently plan our time. Thanks again and we look forward to many more orders!"

"I'll just attach some images/projected stacks using the Lamin1 antibody on some of our tadpole stages. I've seen quite a number of immunostaining pictures over the last years, but this tops them all I must say! As you may know, Lamins line the inside of the nuclear membrane and this gives a fantastic 3D ball-shaped image upon stacking. This antibody worked well in both rabbits and there was no background to be seen."

McGill University - Montréal, QC
Our Director of R&D stated:
"The molar recovery of the peptide was found to be approximately 97% with all the factors adjusted accordingly. This recovery indicated good quality. As we expect from one of our Gold Level Suppliers, we are very pleased with the product and the effort your company has made.

It is refreshing to see your company ethic has not changed. And. to follow-up on your comments concerning your QC protocols; I indeed recall noting you take the extra step. You're a role-model to be followed."


ASRC -USGS, CERC - Columbia, MO
"I have assessed the antisera sent to us in test bleeds 1 -5, and are very satisfied, so far, with its specificity and sensitivity."

Senter for Medisinsk Genetikk og Molekylaermedisin - Haukeland Universitetssykehus
"I have tested the antibodies and found the two antibodies to recognize the desired 7 Kb large peptide on western blots, thank you!"

Best, USGS Conte Anadromous Fish Research - University of Massachusetts, Amherst
"Thanks again for the potent anti-sera. Several bleeds are immunoreactive with a single distinct band of the expected molecular weight-we don't need the affinity!

"Hi Pam. The paper is attached. Yours is the best antibody!! I recommend your company to everybody. Guess what - I got my NIH grant. We will be making more antibodies soon ;-) "

Medical Research Council - London, UK
"We have been testing the antibodies in the lab and they are performing very well, thank you! Thanks for all your help."

Glaxo Smith Kline
"I did receive notifications from Pam as well, and would once again like to thank you both for your diligence in keeping me informed of the peptide synthesis progress. The peptide works great for us!"

Mount Sinai School of Medicine - New York, NY
"We just sent a paper for publication using your antibody. If it gets accepted I will send you a copy. I must say that the antibody works very nicely."

Woods Hole Oceanographic Institution
"On the preliminary results, everything looks good. Just so you know we are very pleased with the antibodies so far!"

University of North Carolina at Chapel Hill School Of Medicine - Department of Pathology & Lab Medicine
"This e-mail is to let you know the peptide experiment worked quite nicely! It has been a pleasure working with your company and I will be sure to pass the word along of your great services."

Glaxo Smith Kline
"I am placing an order for another 50 mg of peptide! We continue to be pleased by the products we receive from you."

University of Puerto Rico
"Thank you very much.... Again, thank you very much for your very efficient service. I will probably contact you in a near future with an additional order."

Emory University School of Medicine
"I obtained your contact information from a colleague at Emory who spoke very highly of your company. I would like to make antibody against WNK4 and WNK1. I wonder if you could help me in this process and give me some ideas on the cost."

The Ohio State University
"I am finishing up the manuscript that will include the data using the fine antibody you manuifactured for us. When I began this work, I spoke with Dr. Fishman about the information that I would need to include in my material and methods section about the making of this antibody - his comments and write-up were much appreciated!"

University of Tampere - Finland
"As per the western blot in my mails (02-05), the experiments using your antibodies went perfect. The immunohistochemistry gave also very nice results.."
