Question

Where is the questionnaire that I should fill out? If it is the note with product number and lot number, I already filled that out in my previous inquiry.

Best regards,

Answer

Thank you for your quick response.

The Questionnaire has been attached to my first response as a word document but I have reattached it to this e-mail as well.

Please could you add further information to the Questionnaire? I am particularly interested in sample preparation, lysis buffer. Have you run a secondary antibody ONLY control (without the sample and primary antibody)? Liver cells/tissues have very high concentration of intracellular proteins. It may be worth increasing the concentration of the blocking agent from 5-10%. Have you had any chance to use BSA rather than milk for blocking?

Could you please confirm the Abcam Order number and the arrival date as well?

I look forward to hearing from you soon.

Question

1) Abcam product code ab7118



2) Abcam order reference number or product batch number lot nr GR27997-6



3) Description of the problem: unspecific bands on western, with using only the secondary antibody (no primary)



4) Sample preparation:

Type of sample (whole cell lysates, fraction, recombinant protein…): tissue homogenates, centrifuged 4000xg, supernatants dissolved in Laemli

Lysis buffer: Laemli (SDS, DTT)

Protease inhibitors: Pefabloc (SDigma-Aldrich) + Leupeptin

Phosphatase inhibitors: no

Reducing agent: DTT

Boiling for ≥5 min? yes/no: 65C 15 min

Protein loaded ug/lane or cells/lane: approximately 10-30 ug protein per lane

Positive control

Negative control



5) Percentage of gel: 4-15% polyacrylamide

Type of membrane: PVDF

Protein transfer verified: the marker, which is blue is gone from the gel, and can be seen on the membrane

Blocking agent and concentration: milk 5%

Blocking time: 1 h

Blocking temperature: RT



6) Primary antibody (If more than one was used, describe in “additional notes”) :

NO PRIMARY ANTIBODY!



7) Secondary antibody:

Species: goat

Reacts against: chicken

Concentration or dilution: 1:5000

Diluent buffer: PBS-T

Incubation time: 1 h

Incubation temperature: RT

Fluorochrome or enzyme conjugate: HRP



8) Washing after primary and secondary antibodies:

Buffer PBS-T

Number of washes: 4-5



9) Detection method: ECL



10) How many times have you run this staining? Two times, with different samples, because I thought first that something was wrong with my samples.

Do you obtain the same results every time? yes

What steps have you altered to try and optimize the use of this antibody? Not optimized, I would like hear first what your suggestions are.

Your original inquiry to Abcam:


Lot number: GR27997-6

Enquiry: Hi, I experience problems with the secondary antibody: I see bands on the blot, without adding primary antibody. This would indicate unspecific binding of secondary antibody to the proteins on the membrane. How do I avoid unspecific binding of secondary ab? Is there any way of more stringent washing (protocol)? WB conditions: 20 ul mouse liver homogenate per lane, blocking 5% milk, detection ECL, 4-15% polyacrylamide gel, dry transfer, secondary 1:5000 diluted in PBS-T 1hr RT, washes 4-5 times 5-15 min. (This protocol worked fine previously with different primary ab made in rabbit, and goat anti rabbit secondaries, and we have not previously experienced unspecific signals from secondary alone) Best regards,

Answer

Thank you for your enquiry regardingab7118 and for taking the time to provide some useful details of the experiments. I am very sorry to hear that you are having problems with this antibody.

Though you have kindly provided some details, it would be much appreciated if I could get some more information which would help me identify the source of the problem.

- Have you run a secondary antibody ONLY control (without the sample and primary antibody)?

- Liver cells/tissues have very high concentration of intracellular proteins. Have you tried loading 5 or ug per lane?

- It may be worth increasing the concentration of the blocking agent from 5-10%. Have you had any chance to use BSA rather than milk for blocking?

Thank you for your understanding and co-operation in this matter. I look forward to hearing from you and hope to solve this problem as soon as possible.
