Laminin antibody | 4C7 (2D8/33)
Mouse anti Human Laminin Alpha 5 antibody, clone 4C7 (5620-0436) used for the identification of alpha-5 laminin from JAR choriocarcinoma cells by immunopercipitation.
Image caption:
Expression and synthesis of laminins by JAR cells.
A) JAR choriocarcinoma cells transcribe lm α1, lm α3, lm α5, lm β1, lm β2, lm β, lm γ2, and lm γ1 chains as shown by RT-PCR. As a reference sample, we used optimized, in-house prepared positive control mix, which contains cDNA from undifferentiated hPSCs, spontaneously differentiated hPSCs as well as from isolated human pancreatic islets. B) JAR choriocarcinoma cells were metabolically labeled with 35S and the cell culture supernatant and matrix deposited by JAR cells were immunoprecipitated using antibodies, which specifically recognize the human lm α1 (400 kDa) and lm α5 (350-380 kDa) chains. The cells showed abundant lm-511 and -111 synthesis.

Mouse anti Human Laminin Alpha 5 antibody, clone 4C7 (5620-0436) used for the identification of lamanin alpha-5 by western blotting.
Image caption:
Reactivity of novel mAbs to LMα5 chain as measured by ELISA, Western blotting and immunoprecipitation. A) Reactivity of the antibodies with rhLMs 411, 511 and 521 by ELISA. B) Reactivity of the antibodies with rhLM511 by Western blotting under reducing conditions. C) Ability of the antibodies to immunoprecipitate laminin-511 from A549 cells' conditioned medium and detection of the LMα5 chain by Western blotting with mAb 4B5. Bands of 300/350 kDa corresponding to LMα5 chain were detected with some of the antibodies.

Mouse anti Human Laminin Alpha 5 antibody, clone 4C7 (5620-0436) used for the evaluation of lamanin alpha-5 expression in human kidney by immunohistofluorescence on acetone fixed cryosections.
Image caption:
Immunohistochemical reactivity of mAb 8G9 in comparison to mAb 4C7 against LMα5 chain.
(A) and (C), mAb 4C7; (B) and (D), mAb 8G9 against frozen sections of human kidney (A) and (B), and skin (C) and (D). The staining pattern of the two antibodies was indistinguishable. In kidney, the antibodies stained glomerular and tubular basement membranes, whereas in skin, reactivity with epidermal and vascular basement membranes was observed.

PLoS ONE 8(1): e53648.
Mouse anti Human Laminin Alpha 5 antibody, clone 4C7 recognizes the laminin alpha 5 chain also known as Laminin-10 subunit alpha, Laminin-11 subunit alpha or Laminin-15 subunit alpha. Laminin is a complex glycoprotein composed of three polypeptide chain complexes. Laminin alpha 5 is expressed in heart, lung, kidney, skeletal muscle, pancreas, retina and placenta, there is little or no expression in brain and liver.
