詳細介紹:
Mouse anti-sTn monoclonal antibody (Catalog # TVBP002) for inflammatory cell ICC and inflammatory tissue IHC assay
sTn antigen (sialyl-N-acetyl-galactosamine O-linked to serine or threonine, Sialyl-galNAc-O-Ser/Thr), a mucin-type O-linked glycan, is a well-established cell surface marker for inflammatory tissues. Its elevated levels have been correlated with inflammation
sTn is the surface marker of inflammatory cells and tissues. Applying our mouse anti-sTn monoclonal antibody (Catglog # TVBP002), we were able to detect a significant increase in the levels of sTn antigen in human gingival fibroblasts under the induction of TNF-α (30 ng/ml) for 48 hours (fig. 1). We also observed an increase of sTn in experimental periodontitis (fig. 2).
Figure 1. sTn was induced in human gingival fibroblasts with TNF-a treatment (30 ng/ml) for 48 hours
Figure 2. sTn was detected in experimental periodontitis using our mouse anti-sTn monoclonal antibody (Catalog # TVBP002) for inflammatory tissue IHC assay.

Mouse anti-CETP(N) mAb
Mouse anti-CETP(N) monoclonal antibody (Catalog # TVBP003) for cholesterol ester transfer protein assay. Specificity: Mouse anti-CETP(N) monoclonal antibody against N-terminal amino acid residues 1 to 12 of human cholesterol ester transfer protein. Antigen used for immunizations: Prokaryotic recombinant protein containing 7 copies of the N-terminal amino acid residues 1 to 12 of the cholesterol ester transfer protein in linear array was used as immunogen for immunization. Storage Buffer: The mouse anti-CETP(N) monoclonal antibody (Catalog # TVBP003) for cholesterol ester transfer protein is kept in PBS. Western blotting Recommended: Working dilution for Western blotting 1:1000. Primary antibody incubate at 25℃ for 60min. Figure 1. Western blotting of human serum cholesterol ester transfer protein with mouse anti-CETP(N) monoclonal antibody (Catalog # TVBP003). Storage and stability: Store unopened antibody at -20℃ or lower. Under these conditions, there is no significant loss in product performance up to one year from the date of purchase. The antibody is stable for at least two months when stored at 4℃. For long term storage, it is recommended that aliquots of the antibody are frozen at -20℃ (frost-free freezers are not recommended). Repeated freezing and thawing must be avoided. Prepare working dilutions on the day of use. Legal consideration: FOR RESEARCH USE ONLY. Application: Cholesterol ester transfer protein (CETP) is a serum enzyme involved in a variety of activities such as catalysis of the non-directional transfer of neutral lipids, mainly cholesteryl ester (CE) and triglyceride (TG), between lipoproteins in plasma. As a result, the levels of CETP may decide the profile of lipoproteins such as HDL, LDL VLDL and chylomicrons in serum. Thus, the regulation of the activities of CETP may be a promising strategy for increasing HDL-C levels and CETP may be used to a possible target to treat atherosclerotic cardiovascular disease and fatty liver.

Mouse anti-CETP(C) mAb
Mouse anti-CETP(C) monoclonal antibody (Catalog #TVBP004) for cholesterol ester transfer protein assay Specificity: Mouse anti-CETP(C) monoclonal antibody against C-terminal amino acid residues 463 to 475 of human cholesterol ester transfer protein. Antigen used for immunizations: Prokaryotic recombinant protein containing 7 copies of the C-terminal amino acid residues 463-475 of the cholesterol ester transfer protein in linear array. Storage Buffer: The mouse anti-CETP(C) monoclonal antibody (Catalog #TVBP004) against human cholesterol ester transfer protein is kept in PBS.

As a result, the levels of CETP may decide the profile of lipoproteins such as HDL, LDL VLDL and chylomicrons in serum. Thus, controlling the levels of CETP may be a good approach to affect the rise of HDL-C and may be a possible target to treat with atherosclerotic cardiovascular disease and fatty liver.

Tn monoclonal antibody
Mouse anti-Tn antibody monoclonal antibody (Catalog # TVBP001) for cancer cell ICC and cancer tissue IHC assay. Tn antigen antibody (N-acetyl galactosamine O-linked to serine or threonine, GalNAc-O-Ser/Thr) (Figure 1), a mucin-type O-linked glycan, is a well-established cell surface marker for tumors. Its elevated levels have been correlated with cancer progression and prognosis (1-5). Applying our mouse anti-Tn monoclonal antibody (Catalog # TVBP001) for cancer tissue IHC assay, we were able to detect a significant increase in the levels of Tn antigen in prostate cancer (6), oral squamous cell carcinoma, colon cancer (7), pancreas cancer and in ductal carcinoma in situ (DCIS) and invasive ductal carcinoma (IDC) of breast cancer, but not in normal prostate, colon and breast tissue. Examination of cervical cancer tissues demonstrated high levels of Tn in moderately to poorly differentiated tumors and low levels of Tn in well differentiated cervical cancer tissues. We also applied mouse anti-Tn monoclonal antibody (Catglog # TVBP001) for cancer cell ICC assay. As shown in figure 2, Tn is expressed on the membrane of cancer cells.
