Search for Certificates of Analysis (COA) by entering the products Lot/Batch Number. Lot and Batch Numbers can be found on a product’s label following the words ‘Lot’ or ‘Batch’.
Documents related to the products that you have purchased in the past have been gathered in the Document Library for your convenience.
How to Find the Product Number
Product numbers are combined with Pack Sizes/Quantity when displayed on the website (example: T1503-25G). Please make sure you enter ONLY the product number in the Product Number field (example: T1503).

How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
This page describes common challenges encountered when lysing cells and extracting proteins prior to Western blotting. Total protein concentration must be determined for these cell lysates. Variables affecting each of these steps are outlined below, as each could affect the sensitivity and reproducibility of the Western blot.
The era of high-throughput proteomics has recently blossomed due in large part to advances in the methods by which proteins and proteomes are analyzed. Improved fractionation techniques, combined with advances in mass spectrometry, have decreased concerns of sample complexity, and directed more focus towards high-throughput techniques.
The possible causes and potential remedies for challenges encountered in the immunoprecipitation-Western blot technique, which consists of cell lysis, formation of the antibody-antigen (immune) complex, precipitation of the immune complexes, and analysis by Western blotting.
Protein quantification methods, reagents, and immunoassay technology for accurately measuring the protein concentrations in a variety of samples.
A wide variety of products for traditional protein quantitation techniques such as BCA and Bradford. Also, products for alternative assays such as Lowry, Micro Pyrogallol and FluoroProfile are also available for total protein determination.
Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
