Bioactivity
(High Mobility Group Protein 1 (HMG1), also known as high mobility group box 1 proteinbelongs to high mobility group and contains HMG-box domain. HMG1 is one of the most important chromatin proteins. This nuclear protein organizes the DNA and regulates transcription. It supports transcription of many genes in interactions with many transcription factors. HMGB1 is secreted by immune cells (like macrophages, monocytes and dendritic cells) through leaderless secretory pathway. Activated macrophages and monocytes secrete HMGB1 as a cytokine mediator of Inflammation. Besides, Tumor Protein p53 (TP53) has been identified as an interactor of HMG1, thus a binding ELISA assay was conducted to detect the interaction of recombinant human HMG1 and recombinant human TP53. Briefly, HMG1 were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100uL were then transferred to TP53-coated microtiter wells and incubated for 2h at 37°C. Wells were washed with PBST and incubated for 1h with anti-HMG1 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°C. Finally, add 50uL stop solution to the wells and read at 450nm immediately. The binding activity of HMG1 and TP53 was shown in Figure 1, and this effect was in a dose dependent manner.)

Activity
(Creatine Kinase, Brain (CKB) consists of a homodimer of two identical brain-type CK-B subunits. CKB is a cytoplasmic enzyme involved in cellular energy homeostasis, with certain fractions of the enzyme being bound to cell membranes, ATPases, and a variety of ATP-requiring enzymes in the cell. The protein reversibly catalyzes the transfer of "energy-rich" phosphate between ATP and creatine or between phospho-creatine (PCr) and ADP. Besides, Fusion (FUS) has been identified as an interactor of CKB, thus a binding ELISA assay was conducted to detect the interaction of recombinant human CKB and recombinant human FUS. Briefly, CKB were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100uL were then transferred to FUS-coated microtiter wells and incubated for 2h at 37°C. Wells were washed with PBST and incubated for 1h with anti-CKB 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°C. Finally, add 50uL stop solution to the wells and read at 450nm immediately. The binding activity of CKB and FUS was shown in Figure 1, and this effect was in a dose dependent manner.)

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” or “synthetic” protein counterparts).
If a protein successfully folds into the correct shape, it is 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.
