Immunoprecipitation - Anti-IGFBP3 antibody [EPR22152-22] - BSA and Azide free (AB239789)

IGFBP3 was immunoprecipitated from 0.35 mg of rat serum with ab220429 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab220429 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10,000 dilution.

Lane 1 : Rat serum 10 μg (Input).
Lane 2 : ab220429 IP in rat serum (+).
Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab20429 in rat serum.

Blocking and dilution buffer and concentration : 5% NFDM/TBST.
Exposure time : 30 seconds.

Both glycosylated (46 kDa) and non-glycosylated (29 kDa) IGFBP-3 are detected in rat serum. The molecular weight observed is consistent with what has been described in the literature (PMID 10352394; PMID : 9698597).

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab220429).

IGFBP3 was immunoprecipitated from 0.35 mg of mouse serum with ab220429 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab220429 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/5000 dilution.

Lane 1 : Mouse serum 10 μg (Input).
Lane 2 : ab220429 IP in mouse serum (+).
