HY-113134S

25-Hydroxycholesterol-d6
25-Hydroxycholesterol-d₆ (25-OHC-d₆) is the deuterium labeled 25-Hydroxycholesterol. 25-Hydroxycholesterol is a metabolite of cholesterol that is produced and secreted by macrophages in response to Toll-like receptor (TLR) activation. 25-hydroxycholesterol is a potent (EC50≈65 nM) and selective suppressor of IgA production by B cells[1][2].

HY-153084

CD19 CAR mRNA (Mouse) 1 Publications Verification		mRNA
CD19 CAR mRNA (Mouse) will express mouse CD19 CAR protein, and can be used in chimeric antigen receptor T cell immunotherapy (CAR-CD19). The CD19 CAR is a chimeric antigen receptor. Among them, CD19 is a CD molecule expressed by B cells (i.e. leukocyte differentiation antigen), an important membrane antigen involved in B cell proliferation, differentiation, activation and antibody production, and can also promote BCR signal transduction.

HY-153084A

CD19 CAR mRNA (Human)		mRNA
CD19 CAR mRNA (Human) will express Human CD19 CAR protein, and can be used in chimeric antigen receptor T cell immunotherapy (CAR-CD19). The CD19 CAR is a chimeric antigen receptor. Among them, CD19 is a CD molecule expressed by B cells (i.e. leukocyte differentiation antigen), an important membrane antigen involved in B cell proliferation, differentiation, activation and antibody production, and can also promote BCR signal transduction.
