CODEX® Barcoded Antibodies

Leinco Technologies manufactures and inventories CODEX® barcoded antibodies and complementary fluorophore-conjugated oligonucleotides (reporter molecules). Providing "Ready to Stain' DNA barcoded antibodies minimizes user optimization for high multiplex imaging. CODEX® can detect over 40 biomarkers in an automated cyclical image acquisition process. Using the fully integrated, high multiplexing CODEX® technology allows an accurate picture of cell neighborhoods and interactions in the tissue microenvironment.

'Ready to Stain' DNA barcoded antibodies are validated according to tissue preparation, such as fresh frozen (FF) or fresh frozen paraffin-embedded (FFPE), and by tissue screened, such as liver, spleen, tonsil, brain, etc. Leinco DNA barcoded antibodies for CODEX® have undergone varying levels of validation and quality testing to assure conjugations are free of unconjugated antibodies and DNA barcodes.

Fluorophore reporter molecules are conjugated to complementary oligonucleotides and matched with barcoded antibodies. The four distinct fluorescent reporter molecules include Alexa Fluor™ 488 (green channel), Alexa Fluor™ 750 (infrared channel), Atto 550 (yellow channel), and Cy5 (bright red channel).

CODEX® Validated Antibodies

Leinco Technologies offers Purified (CODEX® Ready) antibodies that are 'Ready to Conjugate' to oligonucleotides. These antibodies are formulated in conjugate ready buffers to minimize the antibody preparation needed when performing a CODEX® barcode conjugate. CODEX® Ready antibodies are validated according to tissue preparation, such as fresh frozen (FF) or fresh frozen paraffin-embedded (FFPE), and by tissue screened, such as liver, spleen, tonsil, brain, etc.

AffiPure™ Purified Immunoglobulins

AffiPure™ control antibody products are produced from normal serum obtained from multiple animal species (Mouse, Rabbit, Rat, etc.) and that have not been previously immunized. This IgG is purified using multiple methods and provided in a standard PBS buffer. This preparation can be used as a control reagent for immunoassays in which the corresponding polyclonal and monoclonal antibodies are used. In addition, Leinco also offers antibody fragments with specific proteases and isotype controls from Mouse, Rat, and other species. Leinco's AffiPure™ proteins are suitable for use as analytes or controls in assays including ELISA, Western Blot, Immunofluorescence Microscopy, and Immunohistochemistry (IHC).
