E Coli GAL12 Active Protein – Cat# AAA152174 – Bioactivity
E Coli GAL12 Active Protein – Cat# AAA152174 – Bioactivity Bioactivity (Galectin-12 is a member of a family of mammalian lectins known as galectins. The galectins constitute a large family of carbohydrate-binding proteins that function in many systems both intracellularly and following secretion. Galectins contain either one or two carbohydrate recognition domains (CRR) which mediate recognition of N-acetyl-lactosamine-containing glycoproteins. Individual galectins differ in their tissue distribution and in their carbohydrate-binding specificities. Galectin-12 is predominantly expressed in adipose tissue and detected also in macrophages and other leukocytes. It plays an important role in cell-cell adhesion, cell-matrix interactions, macrophage activation, angiogenesis, metastasis, apoptosis. 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 Hu GAL12 with 0.9% sodium chloride injection, add 50uL a serial dilution of GAL12 to each well of a U or V-bottom shaped 96-well microtiter plate. The final well serves as a negative control with no GAL12, 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 GAL12 is 0.781 ug/mL.)

E Coli GAL8 Active Protein – Cat# AAA152177 – Bioactivity Bioactivity (Galectin 8 (GAL8), also known as prostate carcinoma tumor antigen 1 (PCTA1) in human, is a tandem repeat-type galectin. 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. 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 Bovine GAL8 with 0.9% sodium chloride injection, add 50uL a serial dilution of GAL8 to each well of a U or V-bottom shaped 96-well microtiter plate.

293F Cell CES1 Active Protein – Cat# AAA152179 – Bioactivity
293F Cell CES1 Active Protein – Cat# AAA152179 – Bioactivity Bioactivity (carboxylesterase 1 (CES1) also known as Liver carboxylesterase 1 is a serine esterase and member of a large multigene carboxylesterase family. The protein Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs. Hydrolyzes aromatic and aliphatic esters, but has no catalytic activity toward amides or a fatty acyl-CoA ester. Hydrolyzes the methyl ester group of cocaine to form benzoylecgonine. Thus, the recombinant human CES1 activity was measured by its ability to hydrolyze 4-Nitrophenyl acetate (4-NPA) to 4-Nitrophenol. The reaction was performed in 50 mM Tris, pH 7.5(Assay Buffer), initiated by addition 50 uL of various concentrations of CES1 (dilute by Assay Buffer) to 50 uL of 2 mM Substrate 4-NPA(100 mM stock in Acetone, dilute by deionized water). Incubated at 37 degree C for 10min, then read at a wavelength of 400 nm.)

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.
