(Interferon regulatory factor 8 (IRF8), also known as interferon consensus sequence-binding protein, is a transcription factor that plays central roles in the regulation of myeloid cell fate. In both mice and humans, IRF8 is required for the differentiation of most monocyte and dendritic cell subsets, but suppresses neutrophil production. IRF8 can both act as a transcriptional activator or repressor, and it acts as a transcriptional repressor of osteoclast differentiation factors such as NFATC1 and EEIG1. Thus a functional binding ELISA assay was conducted to detect the interaction of recombinant mouse IRF8 and recombinant mouse NFATC1. Briefly, IRF8 was diluted serially in PBS with 0.01% BSA (pH 7.4). Duplicate samples of 100 ul were then transferred to NFATC1-coated microtiter wells and incubated for 1h at 37 degree C. Wells were washed with PBST and incubated for 1h with anti-IRF8 pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody for 1h at 37 degree C, wells were aspirated and washed 5 times. With the addition of substrate solution, wells were incubated 15-25 minutes at 37 degree C. Finally, add 50 uL stop solution to the wells and read at 450/630 nm immediately. The binding activity of recombinant mouse IRF8 and recombinant mouse NFATC1 was shown in Figure 1, the EC50 for this effect is 0.05 ug/mL.)

(Endothelial protein C receptor (EPCR) also known as CD201, is a transmembrane glycoprotein expressed on vascular endothelial cells and functions as a negative regulator of thrombosis. It is expressed most strongly in the endothelial cells of arteries and veins in heart and lung. Mature human EPCR consists of a 193 amino acid (aa) extracellular domain (ECD), a 21 aa transmembrane segment, and a 7 aa cytoplasmic tail. Within the ECD, human EPCR shares 63% and 66% aa sequence identity with mouse and rat EPCR, respectively. EPCR inhibits thrombosis through its interactions with Protein C, activated Protein C (APC), and Coagulation Factors VII, and VIIa. Thus a functional binding ELISA assay was conducted to detect the interaction of recombinant human EPCR and recombinant rat Coagulation Factor VII (F7). Briefly, EPCR was diluted serially in PBS with 0.01% BSA (pH 7.4). Duplicate samples of 100 ul were then transferred to F7-coated microtiter wells and incubated for 1h at 37 degree C. Wells were washed with PBST and incubated for 1h with anti-EPCR pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody for 1h at 37 degree C, wells were aspirated and washed 5 times. With the addition of substrate solution, wells were incubated 15-25 minutes at 37 degree C. Finally, add 50 uL stop solution to the wells and read at 450/630nm immediately. The binding activity of recombinant human EPCR and recombinant rat F7 was shown in Figure 1, the EC50 for this effect is 0.06 ug/mL.)

(C4BPa, also known as C4b-binding protein alpha chain or C4BPalpha, is a subunit of the complement factor C4b-binding protein (C4BP), which plays a crucial role in the regulation of the complement system, a part of the immune system that helps to defend the body against infection.C4BPa is part of a heterodimeric protein complex that consists of two chains, the alpha chain (C4BPa) and the beta chain (C4BPB). It can bind to C4b and C3b, thereby inhibiting the formation of the C3 convertase and preventing excessive complement activation. Thus a functional binding ELISA assay was conducted to detect the interaction of recombinant human C4BPa and recombinant mouse C4b. Briefly, C4BPa was diluted serially in PBS with 0.01% BSA (pH 7.4). Duplicate samples of 100 ul were then transferred to C4b-coated microtiter wells and incubated for 1h at 37 degree C.

(Ephrin A2 (EFNA2) is a cell surface-associated protein belonging to the Ephrin family, which are involved in intercellular communication and cell localization. EFNA2 is mainly expressed in tissues including the brain, heart, lung, kidney and pancreas. And this protein is involved in regulating a variety of biological processes, including cell migration, cell differentiation, and tissue boundary formation, by interacting with Eph receptors. It aslo plays a significant role in the development and maintenance of the cardiovascular system, as well as in the regulation of synaptic plasticity and neuronal circuitry in the brain. A Disintegrin And Metalloprotease 10 (ADAM10), a disintegrin and metalloproteinase, can cleave EFNA2, potentially altering the activity of EFNA2 or its interaction with Eph receptors, thus a functional binding ELISA assay was conducted to detect the interaction of recombinant human EFNA2 and recombinant rat ADAM10. Briefly, biotin-linked EFNA2 were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100 ul were then transferred to ADAM10-coated microtiter wells and incubated for 1h at 37 degree C. Wells were washed with PBST 3 times and incubation with Streptavidin-HRP for 30min, then wells were aspirated and washed 5 times. With the addition of substrate solution, wells were incubated 15-25 minutes at 37 degree C. Finally, add 50 ul stop solution to the wells and read at 450 nm immediately. The binding activity of EFNA2 and ADAM10 was shown in Figure 1, the EC50 for this effect is 1.38 ug/mL.)

What Are Active Proteins?
Proteins are large molecules made up of long chains of amino acids. They will typically fold into a very particular 3-dimensional shape/conformation, that is sometimes referred to as their “native” form, which allows them to work properly in the body. For the purposes of product categorization, AAA Biotech will typically refer to proteins purified from their original animal host as being “native” proteins (this is to signify their difference compared to their recombinant proteins or “synthetic” protein counterparts).
If a protein successfully folds into the correct shape, it will typically display high fidelity characteristics to its original protein in its original animal host and be classified as an active protein, as it will be able to function “normally” in most enzymatic or binding capacities. If it loses this shape, due to factors such as heat or strong chemicals (such as detergents), it becomes inactive and is no longer able to perform its basic functions.
All of the proteins in this category are made under strict quality control, and they are active, pure, low in contaminants, and stable. Most are stored as freeze-dried powders and come without extra tags, so they’re very close to the actual natural/native form.

Active proteins are used primarily in the study of how proteins function, in characterizing/discovering drug interactions, supporting cell growth, running biochemical assays, and in development of diagnostics or therapeutics.
2. How are AAA Biotech's active proteins validated?
AAA Biotech’s active proteins are validated through strict quality control and functional assays to ensure they are properly folded and active. “Active”, though, can be an ambiguous term, so if a specific “activity” or “binding” capability of a protein is of crucial interest to you, please inquire with us prior to purchase, and we will provide further details on how the “Active” modifier was determined to be applicable.
3. Are these proteins tested for biological activity?
Yes, all active proteins from AAA Biotech are tested to confirm they have the expected biological activity before being offered for use. Though, said “biological activity” can be either “enzymatic”, “binding”, or both.
