  • Immunohistochemistry Services

  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

MYL12A / MRCL3 is a nonsarcomeric myosin regulatory light chain. This protein is activated by phosphorylation and regulates smooth muscle and non-muscle cell contraction. This protein may also be involved in DNA damage repair by sequestering the transcriptional regulator apoptosis-antagonizing transcription factor (AATF)/Che-1 which functions as a repressor of p53-driven apoptosis. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 8.

Western blot

Western blot
Anti-Myosin pS19/pS20 Antibody - Western Blot. Affinity purified phosphospecific antibody to phosphorylated regulatory light chain of smooth and non-muscle Myosin at pS19/pS20 was used at a 1:1000 dilution to detect myosin light chain by Western blot on 3T3 cell lysates. A standard urea/glycerol gel without SDS was used to separate phospho forms of regulatory light chain according to mass to charge ratios. In Panel A, reactivity of phosphospecific antibody is shown. In Panel B, reactivity of commercially available pan reactive antibody that detects both unphosphorylated and phosphorylated forms of regulatory light chain is shown. phosphospecific antibody detects both monophosphorylated (pSer20 Mono-P-RLC) and diphosphorylated (pThr19-pSer20 Di-P-RLC) regulatory light chain.

Western blot

Western blot
Anti-Myosin pS19/pS20 Antibody - Western Blot. Affinity Purified Phospho specific antibody to Monophosphorylated Regulatory Light Chain of Smooth and Non-muscle Myosin at pS19/pS20 was used at a 1:5000 dilution to detect myosin light chain by Western blot. Either 13 or 20 ul of a mouse cardiac myocyte lysate was loaded on a 4-20% Criterion gel for SDS-PAGE. Samples were either mock-treated or CLA-treated, as indicated. After washing, a 1:5000 dilution of HRP conjugated Gt-a-Rabbit IgG (LS-C60865) preceded color development using Amershams substrate system. Other detection methods will yield similar results.
