(Retinol-binding protein 4 (RBP4) is the specific carrier for retinol (also known as vitamin A), and is responsible for the conversion of unstable and insoluble retinol in aqueous solution into stable and soluble complex in plasma through their tight interaction. As a member of the lipocalin superfamily, RBP4 containing a beta-barrel structure with a well-defined cavity is secreted from the liver, and in turn delivers retinol from the liver stores to the peripheral tissues. In plasma, the RBP4-retinol complex interacts with transthyretin (TTR), and this binding is crucial for preventing RBP4 excretion through the kidney glomeruli. RBP4 expressed from an ectopic source efficiently delivers retinol to the eyes, and its deficiency affects night vision largely. Recently, RBP4 as an adipokine, is found to be expressed in adipose tissue and correlated with obesity, insulin resistance (IR) and type 2 diabetes (T2DM). The activity of recombinant pig RBP4 was measured by its ability to bind all-trans retinoic acid. The binding of retinoic acid results in the quenching of Trp fluorescence in RBP4. RBP4 was diluted to 50 ug/ml in 50 mM Tris, 10 mM CaCl2, 150 mM NaCl, pH 7.5 (assay buffer) and the retinoic acid was diluted to 400, 200, 100, 30, 10, 3, 1 and 0.5 uM in 95% ethanol. Mixing 112.5 uL of 50 ug/mL rpRBP4 and 12.5 uL of retinoic acid serial dilutions in microtubes and a blank containing 112.5 uL of 50 ug/mL rpRBP4 and 12.5 uL of 95% ethanol, then incubate at room temperature for 30 minutes. Loading 100 ul of the reaction mixtures and blank and read at excitation and emission wavelengths of 280 nm and 340 nm (top read), respectively, in endpoint mode. The result was shown in figure 1, the 50% binding concentration (BC50) is >30 uM.)

(Inhibitor Of Kappa-Light Polypeptide Gene Enhancer In B-Cells Kinase Beta (IkBKb), a subunit of IKK, plays a crucial role in intracellular signaling, especially in inflammation and immune responses. In addition, the binding of TRAF6 to IkBKB is an important link in the immune response, which is not only involved in the initiation of inflammatory signals, but also in its regulation, thus a functional binding ELISA assay was conducted to detect the interaction of recombinant human IkBKb and recombinant mouse TRAF6. Briefly, IkBKb was diluted serially in PBS with 0.01% BSA (pH 7.4). Duplicate samples of 100 ul were then transferred to TRAF6-coated microtiter wells and incubated for 1h at 37 degree C. Wells were washed with PBST and incubated for 1h with anti-IkBKb 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 human IkBKb and recombinant mouse TRAF6 was shown in Figure 1, the EC50 for this effect is 0.11 ug/mL.)

Bioactivity
(Perforin 1 (PRF1) is a pore forming cytolytic protein found in the granules of cytotoxic T lymphocytes (CTLs) and NK cells. Upon degranulation, perforin binds to the target cell's plasma membrane, and oligomerises in a Ca2 dependent manner to form pores on the target cell. The pore formed allows for the passive diffusion of a family of pro-apoptotic proteases, known as the granzymes, into the target cell. The activity of recombinant PRF1 was measured by lysis of erythrocytes using a hemolysis assay. A general procedure is as fllows: two-fold dilute the recombinant mouse PRF1 with 0.9% NaCl, add 50ul a serial dilution of PRF1, 10ul 0.1M CaCl2 to each well, then add 50ul 0.25% rabbit erythrocyte (RaE) to each well and mixed gently. Add 50ul 0.9% NaCl to replace PRF1 in control wells. The plate is incubated for 20 hours at 37 degree C, 5% CO2. The results are shown in Figure 1. It was obvious that the minimal effective concentration of PRF1 is 5ug/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.

FAQ
1. What are active proteins used for in research?
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.
