In vivo grade antibodies have a variety of uses in biological research, from discovery of cell signaling pathways to manipulation of biological systems in animal models for pre-clinical studies. In vivo antibodies from Leinco Technologies have the highest purity standards in the industry, with low endotoxin levels, no detectable aggregates nor leachable protein A. These antibodies are produced in our cGMP and ISO 9001:2015 / ISO 13485:2015 certified facility and are available in custom concentrations and package sizes. In vivo PLATINUM antibodies are also suitable for animal injection as they are pathogen free as determined by the IDEXX Impact I PCR mouse pathogen profile.
Leinco Technologies offers a broad range of purified in vivo antibodies that can be utilized in flow cytometry, immunohistochemistry, spatial biology studies, and more. Compare and contrast in vivo GOLD™ vs. in vivo PLATINUM™ to see how they measure up to our quality standards! Antibodies are available in 1 mg, 5 mg, 25 mg, 50 mg and 100 mg sizes. Bulk sizes, custom concentrations and custom packaging are available on request.

Bioanalytical Data
Figure 1. Quality control of in vivo antibodies: RMP1-14
In vivo antibodies from Leinco Technologies are subjected to extensive QC to ensure high reproducibility between lots. The example in Figure 1 shows the results for different lots of RMP1-14 antibody, directed against PD-1. The lots have consistently high purity as indicated by non-reducing and reducing SDS-PAGE (Fig. 1A and 1B, resp.). Analysis by size exclusion chromatography gave superimposing chromatograms for all nine lots, with overlapping retention times and minimal baseline noise (Fig. 1C). Endotoxin data for eight lots indicated that all lots were below the specification of ≤ 0.5 EU/mg as determined by the limulus amebocyte lysate (LAL) method (Fig. 1D).
