Custom Services

Our feasibility study service is for customers who wish to develop a specific assay. Feasibility studies are ideal for development of new assays, customization of existing assays or outsourcing the development work for proprietary antigens or antibodies.

This type of study is a simple and cost effective way to determine if available reagents are capable of being developed into a working lateral flow assay. Arista Biologicals Inc. has extensive experience developing all types of lateral flow assays using industry standard manufacturing equipment, combining great potential for successful development with a high level of transferability.

Feasibility studies can be performed in as little as two weeks. Reagents can be either supplied by the customer or sourced by Arista Biologicals Inc. Feasibility studies are billed 50% in advance and 50% following the successful completion of the assay.

Arista Biologicals has extensive experience with antibody purification. We offer custom purification service for customers who require affinity, Protein A, or other types of protein purifications for monoclonal and polyclonal antibodies. In close consultation with our client, we determine the best method to target the desired purity, yield and cost, specific to your application. We can follow an existing protocol customized to your specifications. Typical purification service takes 1-2 weeks to complete, depending on the purification method chosen.

If your application requires an antibody of extremely high purity, an affinity support from your antigen is prepared and used for affinity chromatography. Our technical staff can conjugate even the most difficult antigen to purification support columns.

Arista Biologicals Inc. offers custom hapten synthesis and modification along with coupling to a variety of proteins, including Bovine Serum Albumin (BSA), Cationized BSA, Blue Protein, Bovine Thyroglobulin (BTG), and other proteins. We offer strategic regioselective point of attachment and modified linkers.

All conjugation procedures will be on a custom basis, directed specifically to the haptens, the enzymes, or the carrier proteins. They may be matched to your existing antibodies by modifying the strength, the position or the linker of the conjugate. Arista’s turnaround time from receiving client’s material is two to three weeks.

Please inquire for quotations specific to your requirements.

Custom colloidal gold conjugation service of your antibody or protein is available for optimization. For the initial pilot conjugation, we require at least two milligrams to perform a thorough optimization, although we have been successful with as little as 200 micrograms in some cases.
