Epitope Location or Sequence: CH1 has been reported to bind to the peptide region encoded by exon 9a of TPM genes [PMID: 24958154]; this exon is well conserved in all vertebrates. But, the binding of CH1 has also been described to be limited to alpha9a [PMID: 22069507].
Uniprot ID: P04268
Immunogen Sequence: Full length protein
Entrez Gene ID: 396366
Antibody Registry ID: AB_2205770
Additional Information: CH1 reacts strongly with striated muscle forms of tropomyosin, including cardiac alpha-tropomyosin and skeletal alpha- and beta-tropomyosins, but not with tropomyosin isoforms from gizzard (smooth muscle) or chicken embryo fibroblasts. CH1 interferes with the binding of tropomyosin to actin. CH1 recognizes sarcomeric Tm soforms alpha-fast, beta, and alpha-slow with poor affinity for alpha-slow.
Recommended Applications: ELISA, FFPE, Function Blocking, Immunofluorescence, Immunoprecipitation, Western Blot

Storage and Handling Recommendations
Although many cell products are maintained at 4°C for years without loss of activity, shelf-life at 4°C is highly variable. For immediate use, short term storage at 4°C up to two weeks is recommended. For long term storage, divide the solution into volumes of no less than 20 ul for freezing at -20°C or -80°C. The small volume aliquot should provide sufficient reagent for short term use. Freeze-thaw cycles should be avoided. For concentrate or bioreactor products, an equal volume of glycerol, a cryoprotectant, may be added prior to freezing.
Usage Recommendations
The optimal Ig concentration for an application varies by species and antibody affinity. For each product, the antibody titer must be optimized for every application by the end user laboratory. A good starting concentration for immunohistochemistry (IHC), immunofluorescence (IF), and immunocytochemistry (ICC) when using mouse Ig is 2-5 ug/ml. For western blots, the recommended concentration range of mouse Ig 0.2-0.5 ug/ml. In general, rabbit antibodies demonstrate greater affinity and are used at a magnitude lower Ig concentration for initial testing. The recommended concentrations for rabbit Ig are 0.2-0.5 ug/ml (IF, IHC and ICC) and 20-50 ng/ml (WB).
