(PRL (prolactin), also known as luteotropin, is a hormone secreted from the pituitary gland and is best known for its role in enabling mammals to produce milk. PRL plays an essential role in metabolism, regulation of the immune system through activating its specific membrane-anchored receptor (PRLR). A functional binding ELISA assay was conducted to detect the interaction of recombinant goat PRL and recombinant human PRLR. Briefly, PRL was diluted serially in PBS with 0.01% BSA (pH 7.4). Duplicate samples of 100 ul were then transferred to PRLR-coated microtiter wells and incubated for 1h at 37 degree C. Wells were washed with PBST and incubated for 1h with anti-PRL 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 goat PRL and recombinant human PRLR was shown in Figure 1, the EC50 for this effect is 0.1 ug/mL.)

(Tissue Inhibitors of Metalloproteinase 4 (TIMP4) is an enzyme that in humans is encoded by the TIMP4 gene. This gene belongs to the tissue inhibitor of metalloproteinases gene family. The proteins encoded by this gene family are inhibitors of the matrix metalloproteinases, a group of peptidases involved in degradation of the extracellular matrix. The secreted, netrin domain-containing protein encoded by this gene is involved in regulation of platelet aggregation and recruitment and may play role in hormonal regulation and endometrial tissue remodeling. The activity of recombinant bovine TIMP4 was measured by its ability to inhibit rhMMP2 cleavage of a fluorogenic peptide substrate MCA-Pro-Leu-Gly-Leu-DPA-Ala-Arg-NH2 in the assay buffer 50 mM Tris, 10 mM CaCl2, 150 mM NaCl, 0.05% (w/v) Brij-35, pH 7.5. rhMMP2 was diluted to 100 ug/ml and activated with 1 mM APMA at 37 degree C for 1 hour and rbTIMP4 (MW: 24.05 KD) was diluted to different concentrations with the assay buffer. Mix 8 ul of rbTIMP4 curve dilutions, 12.8 ul of activated rhMMP-2, and 59.2 ul of assay buffer, including a control containing assay buffer and the diluted rhMMP-2 and incubate the reactions for 2 hours at 37 degree C. Loading 50 ul of the incubated mixtures which were diluted five-fold in assay buffer into empty wells of a plate, and start the reaction by adding 50 ul of 20 uM substrate. Include a substrate blank containing 50 ul of assay buffer and 50 ul of 20 uM substrate. Then read at excitiation and emission wavelengths of 320 nm and 405 nm, respectively, in kinetic mode for 5 minutes. The result was shown in Figure 1 and it was obvious that recombinant bovine TIMP4 significantly decreased rhMMP2 activity. The inhibition IC50 was )

(Multimerin 1 (MMRN1) is a secreted glycoprotein that consists of multiple subunits, forming a complex with a molecular weight of approximately 150 kDa. MMRN1 is a member of the multimerin family and it is mainly expressed in platelets and endothelial cells. MMRN1 plays an important role in maintaining vascular integrity, regulating clotting and inflammatory responses, among others. In addition, the binding of MMRN1 to Vitronectin (VTN) plays an important role in a variety of physiological and pathological processes, including cell adhesion, migration, blood coagulation, and cell signaling. Thus a functional binding ELISA assay was conducted to detect the interaction of recombinant human MMRN1 and recombinant human VTN. Briefly, MMRN1 was diluted serially in PBS with 0.01% BSA (pH 7.4). Duplicate samples of 100 ul were then transferred to VTN-coated microtiter wells and incubated for 1h at 37 degree C. Wells were washed with PBST and incubated for 1h with anti-MMRN1 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 MMRN1 and recombinant human VTN was shown in Figure 1, and this effect was in a dose dependent manner.)

(Figure. The binding activity of FGF23 with FGFR2.Fibroblast growth factor 23 or FGF23 is a member of the fibroblast growth factor (FGF) family which is responsible for phosphate and vitamin D metabolism. The main function of FGF23 seems to be regulation of phosphate concentration in plasma. FGF23 decreases the reabsorption and increases excretion of phosphate and suppress 1-alpha-hydroxylase, reducing its ability to activate vitamin D and subsequently impairing calcium absorption. Besides, Fibroblast Growth Factor Receptor 2 (FGFR2) has been identified as an interactor of FGF23, thus a binding ELISA assay was conducted to detect the interaction of recombinant human FGF23 and recombinant human FGFR2. Briefly, FGF23 were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100uL were then transferred to FGFR2-coated microtiter wells and incubated for 2h at 37. Wells were washed with PBST and incubated for 1h with anti-FGF23 pAb, then aspirated and washed 3 times.

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.
Learn more in our guide “How active proteins work”.

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.
