ELISA
(ELISA for ADPRS/ARH3 activity 25uM NAD-Biotin and Actived DNA were added into ELISA plate (coated with histone H2A and H2B mixture) with PARP1 in ADPR Buffer and incubated for 1 hour at room temperature. After washing, different concentrations of ADPRS/ARH3 was added into each well and incubated in reaction buffer for 1 hour at room temperature. Following Streptavidin-HRP and ECL incubation, the plate was read in a luminometer or microtiter-plate reader.)
Application Data
(GTPase-Glo assay for KRAS (1-186) activity 1uM rGTP and 0.5 mM DTT was incubated with different concentrations of KRAS (1-186) in GTPase/ GAP Buffer for 60 minutes at room temperature, the total reaction volume was 5ul. To the completed GTPase reactions, we added 5ul of reconstituted GTPase-Glo Reagent to each well and incubated the plate for 30 minutes. Then detection Reagent (10ul) was added, reactions were incubated for 10 minutes and luminescence was measured.)

Application Data
tpp15, Recombinant Protein (Cat# AAA72846)
Application Data
(This protein does not contain any Trp residues. Experience shows that this could result in more than 10% error in the computed extinction coefficient. Therefore, we have meassured the protein concentration by using the colorimetric assay based on the interaction between Coomassie brilliant blue and the arginine and aromatic residues (Bradford Method) and its maximum absorption shifts from 470 nm to 595 nm. The standard curve was performed with the protein BSA. 40 ul of the protein were analysed.DO595 = 0.746)

What Are Recombinant Proteins?
A recombinant protein is created by inserting the gene of interest into a host system like E. coli, mammalian cells, or insect cells. This protein expression method results in the large-scale production of protein in a controlled environment with highly precise structures and functionality. Proteins produced via the “Recombinant” methodology have proven themselves crucial in various biological research areas, including immunology, neuroscience, cancer research, drug delivery and development, and more.
Core Recombinant Protein Product Lines:
- Human: Produced from human genes (e.g., growth factors, cytokines).
- Animal: Derived from mouse, rat, or other animals (e.g., mouse antibodies, enzymes).
- Bacterial: Produced in bacteria like E. coli (e.g., enzymes, bacterial toxins).
- Yeast: Produced in yeast cells (e.g., surface proteins, metabolic enzymes).
- Insect:Expressed in insect cells (e.g., viral proteins, glycoproteins).
- Viral: Derived from viral genomes (e.g., spike proteins for vaccine development).
How Does It Work?
- Gene Identification and Cloning: Scientists first find the exact gene that codes for the protein they are interested in producing, and then create a copy of said gene.
- Recombinant DNA Creation: The copied gene is then inserted into a vector (a vehicle-like plasmid) that can be transported safely into your intended expression host cell/system.
- Host Cell Transformation: The vector (with the foreign gene inside) is shuttled into a host cell. This host can be a bacterium (like E. coli), yeast, insect cells, or mammalian cells, depending on the type of protein or protein characteristics needed.
- Protein Expression:The host cell “reads” the copied gene that was shuttled into it, and begins to produce the gene’s coded-for protein using its own cellular machinery. The host can continue to multiply, and with each new cell, more protein is produced.
- Protein Purification:After enough protein has been made, scientists collect the host cell and separate out the target protein. The protein is then carefully purified so it is free of contaminants, ideally active, and also safe for use.
The result is a purified recombinant protein — a lab-made protein that is biologically identical (in most respects) to the natural/native version.
We take this process a step further, offering recombinant proteins that are produced with precise control over sequence modifications, expression levels, and large-scale production. This ensures high-quality, consistent results that will be able to support your research needs and empower your scientific discoveries.
Some of the expression hosts/systems used in recombinant protein generation by AAA Biotech include:
- Escherichia coli (E. coli)
- Human (Homo sapiens)
- Chinese Hamster
- Yeast
- Insect cells (e.g., Baculovirus expression system)

FAQ
1. What is involved in the purification of recombinant proteins?
The purification process of these recombinant proteins is performed to isolate the specific protein produced by the host cell from unwanted substances. The process generally includes techniques such as “affinity chromatography” to separate the protein from other proteins and impurities. AAA Biotech generally offers proteins ≥ 95% pure, depending on the protein type.
2. What are some examples of popular AAA Biotech recombinant proteins?
Some examples of recombinant proteins include:
Retinoblastoma Protein (Cat # AAA10852) – reportedly used in vaccine research and antibody development.

4. Are your proteins suitable for therapeutic development or only research?
AAA Biotech recombinant proteins are strictly for research-use only and are not intended for diagnostic or therapeutic purposes in humans or animals.
5. What types of expression systems do you use for recombinant protein production?
The production labs use a variety of expression platforms, including bacterial (E. coli), yeast, insect (baculovirus), and mammalian (HEK293, CHO) systems. The expression system used depends on the complexity and intended function/use of the protein.
