Vicatertide SB-01; Peniel 2000	Factor Xa TGF-beta/Smad	Inflammation/Immunology
Vicatertide (SB-01, Peniel 2000) is a polypeptide with both competitive inhibitory activity against TGF-β1 and selective inhibitory activity against human factor XIa (hFXIa, with a K_a of 80 nM for hFXIa). Vicatertide binds allosterically to the two binding sites of dimeric hFXI/hFXIa, while directly binding to activated TGF-β1, selectively blocking the Smad1/5/8 pathway and maintaining low-level activation of the Smad2 pathway to enhance the synthesis of type Ⅱ collagen and aggrecan. Vicatertide inhibits thrombus formation in arteriovenous thrombosis models, and also reduces thrombus weight and thrombus incidence in mouse lung cancer models. Vicatertide can be used for research on degenerative disc disease and thrombosis-related diseases .

	*Coagulation Factor* XI/F11 Protein, Human (HEK293, His)** Coagulation factor XI; Coagulation factor XIa light chain; PTA; FXI; F11	Human	HEK293
	Coagulation factor XI (F11) occupies a central position in the middle phase of the intrinsic pathway of blood coagulation, where it assumes the key role of activating factor IX. This complex process plays a key role in the chain of events that lead to the formation of a blood clot. Coagulation Factor XI/F11 Protein, Human (HEK293, His) is the recombinant human-derived Coagulation Factor XI/F11 protein, expressed by HEK293 , with C-His labeled tag.
