I would recommend running it in a 12.5% or 15% (even better) SDS-PAGE gel, transfer buffer with 0.01% SDS and 15% methanol and transfer it for about 20-30min at 100V.
I would recommend using Tris-Tricine gels. These gels have a better separation performance for smaller proteins but are also more of an effort since you will need 2 different running buffers and a gel spacer between stacking and separating gel (depending on the protocol).
"edit" here is a suitable protocol for Tris-Tricine Gels: http://llinaslab.psu.edu/wp-content/uploads/2013/12/Tris_Tricine_protein_gels.pdf
For the blotting use a 0,2 membrane.
Rasikas settings for your semi-dry seem suitable.
I wish you success
I routinely blot for proteins in the neighborhood of 12-14 kDa using a 4-20% Tris-Glycine gradient gel. I also recommend PVDF membranes for blotting, as they're less likely to let a small protein "pass through" from excessive transfer times.
you can try tris tricine gradient gels and also wash your gel after electrophoresis with distilled water thrice before putting it for transfer,this shall help in eliminating the sds and helping in efficient transfer.use 20% methanol in your transfer buffer.
