You have to use biotinylated oligos.

Saed is right the simplest method is to incorporate a biotinn labelled primer with pcr. there are also kits on the market for klenow labelling if you already have your product

but buying a biotin labelled oligo is easier and cheaper iif you only need one biotin per molecule of product

With biotinylated oligo, I want to label DNA means PCR products with biotin. Have any protocol on this?

Without biotinylated oligo, I want to label PCR product with biotin using PCR ? Have any protocol on this, if so please share your knowledge on this.

Biotin-14-dATP (ThermoFisher # 19524-016) can be incorporated into DNA by:

a) nick translation in the presence of dCTP, dGTP, and dTTP or

b) added to the 3´ end of DNA using terminal deoxynucleotidyl transferase.

I want to incoporate Biotin-11-dUTP Solution (1 mM) into pcr product.

You should prepare a dNTP mix (0.2uM dCTP, dGTP and dATP) but adding biotin-11-dUTP with dTTP (175uM dUTP + 25uM dTTP is a good proportion for uracil-DNA N-glycosylase treatment).
