What Is the Expected AHCY Western Blot Band Size?

AHCY is predicted at 47.7 kDa and observed at approximately 45–48 kDa; the cause of any difference is not established.

What am I looking at on my blot?
Band at approximately 45–48 kDaEmpirical AHCY band in reducing whole-cell and tissue lysates; confirm identity with antibody controls
Single band near 47.7 kDaConsistent with the predicted AHCY monomer mass
Several bands near the expected regionAHCY has isoforms 1 and 2, but distinct migration has not been demonstrated
Band in a cytoplasmic fractionConsistent with the reported cytoplasmic location of AHCY
💡Expected AHCY appearanceAHCY has a predicted mass of 47.7 kDa and an empirical band at approximately 45–48 kDa in reducing lysates; confirm band identity with appropriate antibody controls.

Sample controls for AHCY Western blot

🧪HPA-IHC candidate guidance (verify in WB): For positive controls for AHCY in Western blot, you can use epididymis tissue lysate, where HPA reports high expression.
Positive control: Epididymis (IHC candidate; verify WB)
Negative control: Adipose tissue (IHC candidate; verify WB)
Loading controls: Run GAPDH, β-actin, and a total-protein stain such as Ponceau alongside.
⚠️Feasibility: A clean negative tissue is feasible because HPA reports AHCY as not detected in adipose tissue.

Advanced AHCY Western Blot Tips

Deeper troubleshooting and optimisation questions for AHCY, answered from its protein features.

How should AHCY band migration be interpreted?
Band shift · Use the separately labelled calculated mass and catalog-observed evidence above. A sequence annotation does not establish an observed migration shift. Verify target identity with orthogonal controls.
Could AHCY isoforms produce different bands?
Isoforms · UniProt lists isoforms 1 and 2. Isoform 2 lacks residues 1–28 of the canonical sequence, so it may migrate differently. Confirm isoform detection against the antibody’s binding region; the sequence difference alone does not establish which band is which.
Which AHCY modifications are documented?
PTM · In UniProt canonical coordinates, AHCY has N-acetylserine 2, phosphoserine 183, N6-(2-hydroxyisobutyryl)lysine 186, and phosphotyrosine 193. Isoform 2 lacks canonical residues 1–28, including serine 2. State the numbering convention when comparing these sites with antibody or paper annotations.

The listed phosphorylation and other modifications identify possible sources of molecular variation, but their presence does not demonstrate a visible Western blot shift. Compare treated and control samples under the same conditions before attributing a mobility change to a modification.
Does this guide establish induction of AHCY?
Induction · No general induction response is established by this guide. A pathway or gene-set association is not evidence of induction in a particular specimen. Verify the relevant treatment and control in a target-specific experiment.
How should transfer be checked for AHCY?
Transfer · Standard workflow guidance: verify transfer efficiency for the intended target size before interpreting a weak signal. Use total-protein assessment and optimize transfer for the membrane, gel and apparatus; the labelled catalog values take precedence.
How should blocking be optimized?
Blocking · Standard workflow guidance: follow the A04236-1 datasheet where specified. Otherwise compare 5% milk or 5% BSA in TBST; for a phospho-specific assay start with BSA. Optimize background and specific signal with matched controls.
How should I quantify AHCY in cellular fractions?
Quantitation · AHCY is reported in the cytoplasm, nucleus, endoplasmic reticulum, and melanosomes. Quantify comparable fractions with appropriate loading controls; a change in one fraction alone does not establish a change in total AHCY.
Does the observed AHCY band match its predicted mass?
Interpretation · AHCY is predicted at 47.7 kDa, and the reported Western blot band is approximately 45–48 kDa. The supplied features do not establish why apparent and calculated masses might differ.

Check whether a lower band is consistent with isoform 2, which lacks canonical residues 1–28. AHCY is also reported as a homotetramer, but that feature alone does not identify a higher band. Verify unexpected bands with an independent AHCY-specific check before assigning them.

AHCY Western Blot Antibodies

Catalog antibodies with Western blot application and product-specific WB images. Evaluate suitability with the reported sample, controls and experimental conditions.

Real WB data Western blot analysis of AHCY using anti-AHCY antibody (A04236-1). Electrophoresis was performed on a 10% SDS-PAGE gel at 80V (Stacking gel) / 120V (Resolving gel) for 2 hours. The sample well of each lane was loaded with 30 ug of sample under reducing conditions. Lane 1: human Hela whole cell lysates, Lane 2: human HepG2 whole cell lysates, Lane 3: human A549 whole cell lysates, Lane 4: human Jurkat whole cell lysates, Lane 5: rat liver tissue lysates, Lane 6: rat thymus tissue lysates, Lane 7: mouse liver tissue lysates. After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-AHCY antigen affinity purified polyclonal antibody (A04236-1) at 0.5 μg/ml overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an ECL Plus Western Blotting Substrate (Catalog # AR1196-200) with Tanon 5200 system. A specific band was detected for AHCY at approximately 45-48 kDa. The expected band size for AHCY is at 48 kDa.

Both listed anti-AHCY antibodies have Western blot images. A04236-1 shows a 45–48 kDa band in the specified human cell and rodent tissue lysates; M04236 shows AHCY expression in A549 lysate, with limited experimental detail provided.

Which to pick: Choose A04236-1 if you want documented WB conditions and examples spanning human, rat, and mouse samples. M04236 has a WB image from A549 lysate, but its caption provides fewer details. Both list human, mouse, and rat reactivity.
