Application Notes

Validated Applications:
WB: 1:500 - 1:4000 dilution
ICC/IF: 1:500 - 1:2000 dilution

Published Applications:

Both lamin A and lamin C are recognized by this sera, with lamin A (the slower migrating band on Western blot) sometimes appearing as a doublet. The addition of 0.05% Tween 20 in the blocking buffer and primary antibody incubation buffer is recommended to aid in detection by Western blot. Individual optimization may be required. For immunofluorescence experiments we recommend using paraformaldehyde (PFA) fixation.

Also available as an AbFlex™ engineered recombinant antibody.  For details on the corresponding AbFlex Recombinant Antibody, see Catalog No. 91189.


This Lamin A/C antibody was raised against a recombinant protein corresponding to amino acids 430-545 of human Lamin A.


Cell culture supernatant containing mouse IgG, 30% glycerol, 0.035% sodium azide.

Whole-cell extract (20 µg) of HeLa cells stained with Lamin A/C mAb (Clone 3A6-4C11) at a dilution of 0.5 µg/ml.


Nuclear lamins are intermediate filament proteins that are the major structural component of the nuclear lamina on the inner surface of the nuclear envelope. Lamins A and Lamins C are splice variants of the Lamin A gene. Lamin A/C (CDCD1, LMN1, EMD2) expression is a hallmark of embryonic stem cell differentiation. In addition to adding structural integrity to the nucleus, lamins contribute to the makeup of the nuclear matrix. Lamins also help organize interphase chromatin through interactions with several chromatin proteins, including histones and Lap2, such that alteration in lamin organization results in disruption of DNA replication, transcription and RNA processing.

Positive Control

Active Motif's HeLa whole-cell extract (Catalog No. 40050) can be used as a positive control for Lamin A/C antibody (Clone 3A6-4C11).

Chromatin IP Assays

This antibody has been validated for use in ChIP and/or ChIP-Seq, and can be used with Active Motif's ChIP-IT® High Sensitivity Kit or our magnetic bead-based ChIP-IT® Express Kits. For an overview of all of our ChIP products, please visit our Chromatin IP Page to learn about ChIP products designed for use with Lamin A/C antibody (mAb).

Bridging Antibody to Improve ChIP, MeDIP and IP

Some isotypes of mouse IgG antibodies do not bind well to protein G-conjugated agarose/magnetic beads, which are commonly used in ChIP, MeDIP and IP experiments. Capture efficiency can be improved by including an anti-mouse IgG bridging antibody because it binds with a strong affinity to both the protein G beads and the mouse IgG antibody. By increasing the affinity of the mouse primary antibody for the protein G bead, the Bridging Antibody for Mouse IgG can help improve the results of all ChIP, MeDIP and IP experiments that use Lamin A/C antibody (mAb).

Compatible Secondary Antibodies

Active Motif has developed a variety of high-quality secondary antibodies for most applications, with anti-rabbit and anti-mouse conjugates to a broad line of high-quality fluorescent molecules, as well as horse radish peroxidase (HRP). Visit our Secondary Antibody Conjugates page to find the perfect secondaries for immunofluorescence experiments with Lamin A/C antibody (mAb).


Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.


This product is guaranteed for 6 months from date of receipt.
