IL9 Active Protein – Cat# AAA150065 – Bioactivity
IL9 Active Protein – Cat# AAA150065 – Bioactivity Bioactivity (Interleukin 9, also known as IL-9, is a pleiotropic cytokine belonging to the group of interleukins. IL-9 secreted by CD4 helper cells that acts as a regulator of a variety of hematopoietic cells. This cytokine stimulates cell proliferation and prevents apoptosis. It functions through the interleukin-9 receptor (IL9R), which activates different signal transducer and activator (STAT) proteins namely STAT1, STAT3 and STAT5 and thus connects this cytokine to various biological processes. Besides, Interleukin 9 Receptor (IL9R) has been identified as an interactor of IL-9, thus a binding ELISA assay was conducted to detect the interaction of recombinant human IL-9 and recombinant human IL9R. Briefly, IL-9 were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100uL were then transferred to IL9R-coated microtiter wells and incubated for 2h at 37. Wells were washed with PBST and incubated for 1h with anti-IL-9 pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody, wells were aspirated and washed 3 times. With the addition of substrate solution, wells were incubated 15-25 minutes at 37. Finally, add 50uL stop solution to the wells and read at 450nm immediately. The binding activity of IL-9 and IL9R was shown in Figure 1, and this effect was in a dose dependent manner.Figure. The binding activity of IL-9 with IL9R)

TFPI2 Active Protein – Cat# AAA150120 – Application Data
TFPI2 Active Protein – Cat# AAA150120 – Application Data Application Data (Tissue Factor Pathway Inhibitor 2 (TFPI2) takes part in the regulation of plasmin-mediated matrix remodeling. Inhibits trypsin, plasmin, factor VIIa/tissue factor and weakly factor Xa. TFPI2 doesn’t have any influence on thrombin. TFPI2 also can inhibit MMP activity, which can hydrolyze gelatin under certain conditions. Thus, the activity of TFPI2 can be measured by inhibit MMP-2 hydrolyze gelatin. Gelatin zymography is mainly used for the detection of the gelatinases, 2g/mL was denatured by SDS loading buffer, electrophoresed through sodium dodecylsulphate–polyacrylamide gel (SDS–PAGE; 8% gels) containing gelatin (1mg/mL) with nonreducing conditions. After renaturation, incubate with various concentrations of recombinant mouse TFPI2, then staining with coomassie brilliant blue G250, active MMP-2 would hydrolyze gelatin nearby, which was indicated by the white binds on the gel; if the activity of MMP-2 inhibit by TFPI2, there was none white binds on the gel.The result was shown in figure 1.As the figure 1 shown, MMP-2 can be inhibited by recombinant mouse TFPI2 at least 2.5g/mL.)

E Coli GAL3 Active Protein – Cat# AAA152172 – Bioactivity Bioactivity (Galectin 3 (GAL3) is a member of the lectin family, of which 14 mammalian galectins have been identified. It is also a member of the beta-galactoside-binding protein family that plays an important role in cell-cell adhesion, cell-matrix interactions, macrophage activation, angiogenesis, metastasis, apoptosis. The protein also has been demonstrated to be involved in cancer, inflammation and fibrosis, heart disease, and stroke. GAL3 is expressed in the nucleus, cytoplasm, mitochondrion, cell surface, and extracellular space. It also can agglutinate red blood. In this case, we chose rabbit erythrocyte (RaE) to assay its ability of agglutination. A general procedure for hemagglutination assay (or haemagglutination assay; HA) is as follows, two-fold dilute the recombinant mouse GAL3 with 0.9% sodium chloride injection, add 50uL a serial dilution of GAL3 to each well of a U or V-bottom shaped 96-well microtiter plate. The final well serves as a negative control without GAL3, replace with 50uL 0.9% sodium chloride injection. Then add 50uL 1% rabbit erythrocyte to each well and mixed gently. The plate is incubated for 3 hours at room temperature. The results are shown in Figure 1. It was obvious that the minimal effective concentration of GAL3 is 3.1ug/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.

Key Applications of Active Proteins


1. Scientific Research


  • Aid in the study of how proteins function in the body

  • Aid in understanding various disease processes


2. Drug Development


  • Powerful tools to investigate how potential drugs interact with specific proteins

  • Ideal for identifying drug targets


3. Cell Culture


  • Are routinely utilized to support cell growth and function (e.g., using exogenous growth factors)

  • Can be used to promote cellular development into specific types (differentiation)


4. Diagnostics


  • Regularly utilized in tests to detect diseases or infections (e.g., COVID-19, cancer)

  • Note: All products are strictly for research-use only (RUO).


5. Therapeutics


  • Some active proteins are used directly as treatments (e.g., insulin, enzymes)

  • Note: All products are strictly for research-use only (RUO).


6. Vaccine Development


  • Used to create or test vaccines by mimicking parts of viruses or bacteria


7. Biochemical Assays


  • They can facilitate the characterization of enzyme activity, binding strength, or protein interactions in lab tests

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.
