In vivo grade antibodies have a variety of uses in biological research, from the discovery of cell signalling pathways to the 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 their 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 (see table 2 below).
GOLD™ vs. PLATINUM™ in vivo Antibody Quality Standards:
| Specifications | In vivo GOLD™ MAbs | In vivo PLATINUM™ MAbs |
|---|---|---|
| Binding validation determined by WB, FC or ELISA | Yes | Yes |
| Endotoxin level determined by the LAL method | ≤ 1.0 EU/mg | ≤ 0.5 EU/mg |
| Antibody aggregation screening by analytical SEC | ≥ 95% monomer | ≥ 98% monomer |
| Purity by SDS PAGE | ≥ 95% | ≥ 98% |
| Formulation for in vivo use | No preservatives No stabilisers No carrier protein Sterile PBS pH 7.2 – No K+ or Ca2+ Concentration: > 5mg/mL | Functional grade preclinical antibodies are manufactured in an animal-free facility using only in vitro protein free cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates. |
| Murine pathogen screening | Not applicable, see PLATINUM functional grade antibodies | Pathogen tested (IMPACT1) (see table) |
| Applications | In vivo functional studies and may be used for WB, FC, IF or IHC | |
| Product Preparation | Functional grade preclinical antibodies are manufactured in an animal-free facility using only in vitro protein-free cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates. | |
| Storage and Handling | Use a manual defrost freezer and avoid repeated freeze-thaw cycles. • 1 month, 2 to 8 °C under sterile conditions, as supplied. • 12 months, -70 °C under sterile conditions. | |
