一般描述
ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies.Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.

目标描述
Transmembrane protease serine 2 (UniProt: O15393; also known as Serine protease 10, TMPRSS2) is encoded by the TMPRSS2 (also known as PRSS10) gene (Gene ID: 7113) in human. TMPRSS2 is a single-pass type II membrane protein of the peptidase S1 family that contains a cytoplasmic domain (aa 1-84), a transmembrane domain (aa 85-105), and an extracellular domain (aa 106-492). Its peptidase S1 domain is localized to amino acids 256-489. It is reported to be proteolytically processed by an autocatalytic mechanism generating the transmembrane protease serine 2 non-catalytic chain (1-255) and the transmembrane protease serine 2 catalytic chain (256-492). TMPRSS2 is shown to proteolytically cleave and activate viral spike glycoproteins, which facilitate virus-cell membrane fusions. It is reported to facilitate human SARS coronavirus (SARS-CoV) infection via two independent mechanisms: proteolytic cleavage of ACE2 that promotes viral uptake and cleavage of coronavirus spike glycoprotein, which activates the glycoprotein for cathepsin L-independent host cell entry. TMPRSS2 is highly expressed in the prostate tissue and lower expression is observed in the epithelia of the colon, stomach, epididymis and breast tissue. Some expression has also been reported in pancreatic acini, hepatic bile ducts, testicular Leydig cells and the kidney. Its expression levels are significantly elevated in both neoplastic prostate and in the epithelium of prostatic hyperplasia. Two isoforms of TMPRSS2 have been described that are produced by alternative splicing. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

外形
Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.
重悬
300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.
储存及稳定性
Recommend storage of lyophilized product at 2-8℃; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8℃, or -20℃ for long term storage. Avoid repeated freeze-thaws.
