Antibody performance is an important consideration in research workflows, where specificity, consistency and reliability can influence experimental results. Evaluating antibodies under actual laboratory conditions can help researchers assess their suitability before making a purchase. Thermo Fisher Scientific is offering researchers the opportunity to request free samples of selected Invitrogen™ antibodies to test their performance in their own experimental conditions.
The programme provides access to more than 147,000 eligible Invitrogen antibodies, allowing researchers to evaluate antibody quality and consistency before purchasing. The samples are available at no cost, with no purchase necessary, giving laboratories an opportunity to assess their performance in relevant research applications.
Evaluating Antibody Performance Across Research Applications
Invitrogen antibodies are available for several laboratory applications, including Western blotting, flow cytometry, immunocytochemistry and immunofluorescence, and immunohistochemistry. Researchers can select from the eligible antibody range according to their experimental requirements and assess performance using their own laboratory conditions.
The free sample programme is designed to help researchers evaluate antibody characteristics, including specificity, consistency and reliability, before committing to a purchase. Testing samples within existing experimental workflows allows laboratories to determine whether an antibody meets their research requirements.
Free Sample Programme Eligibility and Conditions
The offer is subject to specific eligibility requirements. Researchers must not have previously purchased the antibody they are requesting, and the programme is limited to one sample per customer. Samples can only be shipped to institutional addresses; residential and personal addresses are not eligible.
The programme is available in the United States, excluding Puerto Rico, and Canada. Requests must be submitted by December 31, 2026, or before sample supplies are depleted, whichever occurs first. Sample volumes range from 10 to 50 µL, and delivery may take up to seven weeks.
Researchers can browse the eligible antibody selection and request a free Invitrogen antibody sample from Thermo Fisher Scientific to evaluate its performance under their own experimental conditions before purchase.
