REFINE the way you purify your proteins

REPLACE your conventional columns

REDUCE your hands-on time and costs

Pro-Chem is a life science R & D and manufacturing company headquartered in the United States. Our mission is to
supply innovative sample preparation and protein purification tools for research scientists and clinical customers in
public sector institutes and industry. Pro-Chem is celebrating its 4th anniversary since the market introduction of
its first product range, BJP static ultrafiltration concentrators for the clinical customer. We launched our new
range of innovative and patented Proteus rapid protein purification kit products in early 2004 for our life science
research market. Our current Proteus spin and vacuum column kit range supports both
antibody and
his-tagged protein purification.

Proteins are our business: we focus on quality and ensuring that we exceed our customer's expectations.

For faster sample loading flow rates with the ProVac Kit, we have introduced the Peristaltic Pump Collar (Cat No: V-PCC). See the download section for a PDF of the instruction sheet.

Nickel-metal chelate agarose resin

Premium Nickel-charged metal chelate agarose resin is now available in 25 ml and 100 ml quantities. Please contact us for pricing and performance specs.

NEW Vacuum column kits for antibody purification

Have you ever wanted to purify monoclonal antibodies from large volumes (up to 2L) of dilute cell culture supernatants, such as those derived from T-flasks? If the answer is 'YES', call or E-mail us to register your interest.

Recombinant protein purification kits

Kits is our business! New Proteus IMAC Mini and Midi kits for the rapid purification of 6xHis-tagged proteins. Read all about the New Kit on the Block in the May edition of Lab News. Click on the Proteus IMAC button for more information about our innovative pre-packed agarose spin column kits.

BJP static urine concentrators

A new article entitled "Power of Concentration" has been published in Medical Laboratory World (MLW), the magazine for Laboratory Medicine. Download a free PDF of the article from the BJP Download Area of the Pro-Chem website.


Proteus spin columns are convenient and easy to use. Kits are supplied with powerful, affinity and single step spin columns, clear and unambiguous protocols, a detailed reference handbook, desalting/buffer exchange columns and ready-to-use buffers. Multiple samples can be purified at the same time with high reproducibility for rapid purification of your antibodies with the Protein A or G antibody purification kits or 6xHis-tagged recombinant proteins.

Applications: Rapid, cost-effective and easy-to-use antibody purification from serum, ascites or tissue culture supernatant and 6xHis-tagged recombinant protein purification from bacterial cells, insect vectors, mammalian cells and yeast.
 


Hands-free loading of large volumes of low concentration antibodies now comes in kit format. Monoclonal antibody concentrations, derived from T flasks, are typically between 5 and 50 µg/ml. 225 cm
2 T-flasks with a maximum working volume of 370 ml are commonly used for monoclonal antibody production. Even more expensive production methods using roller bottles only produce monoclonal antibodies in the range of 10 - 200 µg/ml.

The ProVac Protein A and G kits are designed to concentrate and purify antibodies from large volumes of dilute cell culture supernatants (up to 2 L) using vacuum as the driving force.

Applications: High speed, hands-free concentration and purification of large volumes of dilute cell culture supernatant without the need of a centrifuge.
 


These static concentrators are designed specifically to meet the demands of a busy protein reference laboratory concentrating urinary BJP.

Pro-Chem’s BJP concentrators are offered in 5, 10 and 20 ml bench top units. The BJP static concentrators have true walk-away operation which will increase your laboratory throughput dramatically and are at least 20 % cheaper than the leading device with recoveries in excess of 95 %.

Applications: Hands-free concentration of proteins for identification of monoclonal gammopathies by urine protein electrophoresis or immunofixation electrophoresis.
 

Parallel purification of 6xHis-tagged proteins from E. coli cell lysates using Proteus Mini Metal Chelate spin columns.

Recovered IgG capacities of Protein A (yellow) and Protein G (purple) vacuum columns using rabbit serum over 5 bind-wash-elute cycles (500 mmHg constant vacuum).
