| 应用 | Western Blot(0.1 µg/mL) |
| 目标/特异性 | Detects mouse TSLP in direct ELISAs and Western blots. |
| 使用方法 | Western Blot: 0.1 µg/mL Neutralization: Measured by its ability to neutralize TSLP-induced proliferation in the BaF3 mouse pro‑B cell line transfected with mouse IL‑7 R alpha /CD127 [Park, L.S. et al.

| 背景 | Stromal Lymphopoietin (TSLP) was originally identified from the conditioned medium of a mouse thymic stromal cell line as a protein that promoted the development of B cells. The activity of mouse TSLP overlaps with, but is distinct from, that of mouse IL-7 (1). Mouse TSLP cDNA encodes a 140 amino acid (aa) residue precursor protein with a 19 aa signal sequence. Within the mature region, there are three potential N-glycosylation sites. The Sf21 cell expressed rmTSLP is likely to be glycosylated at all three sites, as three major glycoforms were visible on SDS-PAGE (Figure 1). Insect cells are known to express relatively simple and homogeneous N-glycans that mainly belong to the high mannose type (2). This recombinant protein was found to be an excellent substrate for N-specific glycosidases such as Endo F3 (Figure 1). The majority of the glycans on rmTSLP can be readily removed by Endo F3. However, a small percentage of the glycans is somewhat resistant to Endo F3 digestion, possibly lacking core fucose, as it is known that core fucosylated N-glycans are strongly preferred substrates for Endo F3 digestion (3). |

Cell Proliferation Induced by TSLP and Neutralization by Mouse TSLP Antibody. Recombinant Mouse TSLP (Catalog # 555-TS) stimulates proliferation in the BaF3 mouse pro‑B cell line transfected with mouse IL‑7 R alpha /CD127 in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse TSLP (7.5 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse TSLP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF555). The ND50 is typically 0.1-0.4 µg/mL. |
