WB markers

[F3nt0n]

Hi guis, recently I ran for the first time a Western Blot + immunodetection analysis on few specific proteins and their antibodies;

Beta-actine: 1°Mc Ms β-actin / 2°GAM-HRP
PCNA: 1°Mc Ms PCNA / 2°GAM-HRP
Occludine: 1°Pc Rb OCC / 2°GAR-biotin / 3°s-HRP

I got the following results:

Since i'm quite new to this, I really wondered what those other lines were (beside the molecular ladder). The saturated lines are the proteins (of that I'm sure), but lighter ones are unknown to me.
Also I wondered wether it is possible to find a copy of the right molecular ladder somewhere online, since I lost my copy.

Thank you in advance
